Hello everyone, thanks for approving me! <3 I was searching as a guest last night for answers, but i was unsuccesful.. If a thread with this question already exists, PLEASE point me to it so i can educate myself. I also tried to ask a few questions on the Growdiaries site, but that limits you to 280 Characters and that is not even remotely enough to explain the (ill call it mini problem) im having. I am 9 weeks into my very first grow. After some extensive research on ADHD, I chose one of the exotics, a landrace heirloom sativa, Dr. Grinspoon as the one i want to grow, thinking the end result will help my other half to be motivated and productive during the day. (But thats not the question.) Following all Advanced Nutrients calculators online and guide sites specifically made for Advanced nutrients and growing in coco. The recommended amounts per litre are somewhat reasonable when you look at them, i mean its only reasonable to have 4ml A&B per litre of water during late flower right? Well my TDS pen says otherwise. From what ive gathered, Early seedlings like to be at a range of 300-500EC Early and mid veg it likes to be at a range of 1.1-1.5 and early and late bloom it likes to sit at 1.7-2 (average numbers ive gathered over many different sites and forums) That is understandable and easy to follow. The problem comes here: Even though i am on week 9, because of some complications dring early seedling phase, my Dr.G didnt develop very fast, so i am currently using nute strength for week 3 of veg. The recommended amount of nutes at this stage is 3ml(A&B) of sensi grow and 1.5ml of vitamin-B52 per litre. That brings my 1 litre of water all the way up to 2.2 and im not even at full recommended dosage, or not yet using any supplements that ill have to be using during flowering. That panicks me a little and i dont really want to give that to my G as i already stressed it plenty during early veg with transplanting it into a massive pot with poor drainage. What i do is, i add all the recommended amounts, and then i add 250ml of extra bottled water (using still bottled water from the supermarket that reads at 0.18) to bring the EC down to 1.7-1.9 which Doc seems to be okay with. My question is: Is this right? i mean when i add that 250ml extra water to dilute the feed, the recommended measurements stop being per litre and begin being per 1.25 litre. Is that right thing to do? what happens when i reach full recommended strength and it skyrockets the EC all the way up to 3 (and i know it will considering the nubers im having right now). Do i still keep diluting it with more fresh water until i reach the recommended EC? Or do i keep the feed measurements at 1 litre ignoring the EC levels? I already burned the plant when i had the poor drainage situation and the EC rose up to 5 and i had to transplant it to fresh medium so it wouldnt continue dying. Doesnt diluting the feed made with the recommended amounts also lowers the strength, making the feed weaker than what is the recommended? Any Info would be very much appreciated, and again, i was searching all night to find this answer, and its been bothering me for the last few weeks, If an answer or a similar topic exists already and i missed it PLEASE point me to it so i can read and gather info Thanks for reading and sorry if its too long.

Hello everyone! I think its my 12th grow so far, I've been trough many deficiencies, bugs, fungus and other enviromental problems. I have a situation that confuses me and feeling in a dead-end. Maybe some experienced growers can help me. Before the pictures, some background: I have my first indoor where i grew for 3 years and a half. Plants are doing great, growing in klassman ts3 + 30% perlite, 7 liter pots with powder feeding full pack for veg/flower, EC+pH measurements around 800 μS/cm for early veg ----> 2200 μS/cm around week 6 of flowering and then root cleanup for 2 weeks (tap water is pretty good, with 230 μS/cm and pH 7.0). pH is always around 6.0 with some oscilation up and down to 5.6 and 6.5. The lights are COB leds (1.5m2 with 900w of those chips, 18x50w, 10 x 6000K + 8 full spectrum). VPD in optimal range for each stage, since I have HR+Temp under control. Weed coming from there is quite beautiful. The plants are all regular, feminized, mixed between Sweed labs, Dutch passion and R-kiem seeds. So, the problem here is the new indoor I recently installed. The setup is almost the same as the other, it's a 80x80cm tent and I changed the light. I got a level-up light (https://omnigro.com.ar/producto/proled-550d-dimerizable-20-220w/). Sorry it's in spanish since I'm from Argentina. 220W, Ppfd 602 moles/m2/s on a 80x80cm surface. Spectrum 380 -780nm – 3500k with far red and no UVA/B. CRI 85%. The plants are going down, and I'm kinda lost. With the same setup except for the light, one indoor is doing great, the other is not. In this new indoor I have 5 plants from Sensi seeds + Dutch passion, started from seeds bought in Barcelona. They are in week 3 of flowering. 2 weeks ago (first week of flowering), the runoff water EC was 1200-1600 μS/cm and pH 6.4, when I realized some deficiencies (by the way I usually dont add any nute the first week of flower, to give them some time to uptake the grow nutes). I tought that EC was okay but nut too high so added half the dose of powder feeding (hybrids + calcium) to see if they recover, around 1000μS/cm . They did not recover, the went the opposite way. Today I checked again the runoff. EC was 1450-1650 μS/cm and pH 6.3-6.5. Pictures below My first thought since the only diference with the other indoor doing great is the light, is that i'm underfeeding with the plants under this new light. Since VPD is optimal, pH is okay, maybe the plants are asking way more EC to grow properly than the other grow. I didn't do any big feeding yet cause i'm afraid it could damage the plants even more with a nute lockout. Sorry for the long post. I read you. Thanks in advance

Hello there! I'm wondering if you guys out there could chime in with your solutions to hard water fixes . It’s come to the point where I have to sort out my water situation,As I’m getting lock out with touchy strains . Any easy RO systems out there ? Maybe one that could fit to my shower ? Or one that can be fitted on only when I’m needing to use it? Any UK suggestions would be helpful!

Hey, If I’m saving to invest in the best possible extraction set up I can afford is the controller a important part of this set up? Been looking mostly at EC fans,filters and ducting but is the controller a big player in the environment foundations

Hi All, so i guess i better start with a little back story to my current situation! Ive been growing for awhile and have used the same setup now for quite some time, MH for Veg and HPS for flower. I'd been considering upgrading to LED for awhile and have been following folks on here to see how they have been getting on. I decided to get a Scopex 900 when i sore they were available at just under 600 quid from DIYLED, a proper bargain by anyones terms! Now im in a 1.2m square tent (upgrading to 1.5m planned for my next round) so i new that the light was gunna be more than i needed for this round. So i decided to start things off the way i always do under a CFL to start,, then once potted and onto the wilma under a 250w MH. All was going well, ladies were topped and all 4 were looking grand, lush health new growth and no signs of anything but what was looking to be a outstanding round. So with everything running smoothly and the ladies looking in good shape (just shy of 7 weeks from seed) i decided to break out the LED and see what all the chat was about. This unfortunately this was the start of everything going very wonky and was just over two weeks ago now. First issue was temps, which i think may have cause a bit of shock as at one point they dipped to 19 for a short period. However i managed to get temps to sit between 23 and 29 with lights on and off for the following week or so then refined that range further. Second issue was the fact id been running a 24hr on veg, with MH this was ok but i think the 350w of LED was too much to run for 24hr straight so introduced a 20/4 cycle. Third issue was EC,, now at first i thought i had over fed cos i got what looked like burnt tips, EC was at 0.9 so i dropped it down a couple of points,, but very quickly realised that i had a falling EC ( and the ladies looked hungry) and upped my EC every day/every other as the RES EC just kept on falling after 12hrs or so,, this went on for 9 days, until i hit a RES EC of 1.9. By this time i thought it best to do a fresh RES as all this topping up is never a good idea for obvious reasons. So 4 days ago i did a fresh RES at 1.8 EC. And within 12hrs the opposite started to happen,,, the EC had risen 1.9! So over the last three days ive been going in revers,, every time checking the EC to find that it has climbed back up and then me lowing the EC by adding fresh RO,, until this morning when ive knocked it all the way down to 1.0. Suffice to say the ladies are not happy,, i dont know if one of them is gunna be recoverable and over the last 72hrs another one is looking proper sick. I think they have lock out,, but not sure what else i can do. I also think there is an underlying deficiency which is why i cant nail my EC. Ive suspected it was a MAG issue and have tried some foiler feeding a couple of times but to no effect. I havent wanted to introduce anything else feed wise into the RES as the rising/falling issue has not been solved. Sooooooooo, here are the details and some pics (taken 2 days ago) of my set up to provide a little more clarity to anyone reading. I will add close up pics from today as things are looking worse. This LED malarky has been a steep re-learning curve to say the least but with my environment now steady with temps between 23.5 and 28.5, EC @ 1.0 i dont know how else to combat the lock out/deficiency issue thats now causing havoc. Wilma 4 pot hybrid dripper + DWC. (decent roots in the res for all but the sickest looking lady) Drippers are on for 15mins 4 times during the light cycle. Advanced nuets A & B with RO water, system is chilled with water temps steadily between 20 & 21. A little silver bullet added to prevent pathogens. Scopex 900 running @ 360w hung at aprox 80cm above canopy in a 1.2m sq tent, 3 fans internally circulating the air + temp controlled extraction. Air temps are between 25-28 lights on and 23.5-26 lights off.

Hi All. My tapwater has always been 0.1 to 0.2 ec, well today it seems to be fluctuating between 0.6 and 0.9. The ec meter reads the calibration fluid correctly. Im not a regular grower, so most of the time I wouldnt have a clue what the ec of the tapwater is, but my last two grows it was pretty steady, certainly not 0.9! Are fluctuations like this common? I hope it doesnt persist, a base ec of 0.9 would be a huge pain I imagine.

Good evening growers, Setup: Hydro drain to waste. Going into week 1 of flower. Strain: RQS Green Crack Punch Using Shogun nutrients. Silicon Ph down to 5.8 A & B Katana roots Calmag Zenzyme Sumo boost. During veg i went up to 1.6 EC So I am starting week 1 of flower at 1.6 EC & will increase it by .2 each week. What I want to know is do i have the right idea? Thanks

Hello, Looking for some advice, New to coco, about 10 days into early veg with some ICC in 2l pots estimate around 3 or 4 days til re pot up to 16L as roots just starting to show at bottom of pot. like a plonka already made a rookie mistake and only fed 24hr water for first 2 feeds, as i am now led to believe i should of at least started with a rhizo 2ml per L 0.6 EC i have been feeding every other day for first week to give the roots some growth, began feeding every day on day 7. from the start i have been feeding them 300ml and been getting 75ml to 100ml in run off so a good bit over the 25% minimum required, the clones were well established in rockwool. from day 7 plants have been on (ml per 10L) rhizo 20ml calmag 2ml superthrive 3ml zenzime 2ml Then ECd with CANNA A & B to 1.0 usually that's usually around 10ml of each PH down to 5.8 Now here comes the kicker testing the run off, consistently i have been getting readings of 0.4/0.6 EC 6.0ph, im assuming this isnt normal and is a sign the plants want more nuets as they are using up a good amount of the EC, little bit nervous of increasing the EC already as i read early veg should be around the 0.8EC mark plants look perfectly happy at the minute but i am by no means an expert........just an apprentice.... Environment sat between (25C RH 40% lights on) (21C 50% RH) lights of (18/6 cycle) i am using a blue lab truncheon and ph monitor for those wondering. Any advice much appreciated, Thanks again JB

Firstly i will admit that i still have my growing L plates on as i am still a novice in the game, however once i start looking into things and taking an interest i tend to become a nerd and spend to much time researching. Granted i am trying to run before i can walk, but the subject interests me and id like to possibly test it out at some point in the future. I have been seeing a few growers running extremely High EC levels recently ( any where from 5-8EC ). To some one like me who constantly sees "less is more" and people hitting nice results from 1-1.2 EC this seems beyond ridiculous, however the results and the science speak for themselves and i can't argue with them. Some of the growers using these levels are doing so under LEDs and talk about the plants transpiration being dramatically affected by the switch to LED to the point where plants require twice the E.C level just from being used on LED alone. Apparently LEDs cause the plants to transpire less than half that of tradition CMH/HID in which case twice the nutrient EC level was needed to give the plants the correct amount of nutrition in a smaller volume of water. Another thing to note is that the strain also plays a factor in weather or not plant can take any given EC solution as it was said some plants could take 8EC upwards, where as other would not react kindly to anything over 1.6 This all massively interest me as its out of the "norm" for your average grower and is something that seems to be getting very good results interns of quality and yield. very curious to know what @GSZZ @tokenroll@Owderb@badbillybob think, sorry to tag you guys. In my short time on here you guys have been the main members to stick out and be very knowledgable so curious to know what your options are!

Hello there Looking for some advice please. I am about to start my third hydro grow in a Wilma 8 pot system bought in 2011. Previously and pretty successfully I had followed a feed chart in the Growell catalogue. This time round and following reading a couple of articles on importance of staying on top of EC I have made a rather impulsive purchase of a Bluelab Truncheon, however back home and ‘out of the box’, I have a couple of questions… Firstly, the Wilma involves completely weekly reservoir change. Following a daily EC reading is it basically a case of adjusting basic nutrients (Samurai G&B in this case) or water in the reservoir as necessary, or would other aspects of the feed regime need adjusting maybe daily? Secondly, particularly into flowering, moving plants off the top of the reservoir for water/ nutes etc is highly disruptive once a week let alone throughout the week, assuming a daily EC check and necessary adjustments of water and nutes, is it usually possible to manage all this through the small(ish) hole where the dripper pipe feeds into the reservoir or will plants need to be moved around more than usual within the usual weekly res change? Basically, how do you guys using a Wilma get on with using EC wands like Bluelab and managing nutrients thereafter? Obviously, I want the best for the plants and would like to understand this technology but is it practical for use with my old Wilma or should I just stick with the feed chart? Any thoughts much appreciated! YP

Hi all. Ive just bought a Bluelab EC Truncheon and would like any aditional info in using it and general info on EC. Im in Hydro with AN GMB nutes and a small Voodoo Juice not going to use boosters i want to keep it simple. Ive alreay read about using the nutea at a lower strength and build up as they can be abit strong but with an EC meter ill be able to monitor it properlt for once, so here is the info ive gathered from browsing the forums. If anyone can add/correct anything or give knowledge the thanks in advance. ---------- Small plant needs 400-600ppm, bigger plant 700-800 and heavy flower needs 900-1200 max. if, as your tank levels drop, the e.c level rises, = too much fert if, as the tank level drops, the e.c drops, = not enough ferts 13/6 - w1 - pop bean - mix 1f 1r ---------- Small plant needs 400-600ppm, bigger plant 700-800 and heavy flower needs 900-1200 max. if, as your tank levels drop, the e.c level rises, = too much fert if, as the tank level drops, the e.c drops, = not enough ferts --------- Advanced Nutrients use EC scale 700 eg 2.4EC x 500 = 1200ppm (500 scale) or 1200ppm / 500 = 2.4EC 2.4EC x 700 = 1680ppm (700 scale) or 1680ppm / 700 = 2.4EC ---------------- General Grow Regime Example Vegetive feeding 0.6-1.2 EC Flower 1.2-1.6 EC Flowering formula for 8 weeks using Sensi bloom A+B, Big bud and Overdrive.

Week4:-Add equal parts of sensi bloom A+B to reach 1.1EC then top off with Big Bud until a reading of 1.5 is reached. Week5:-Add equal parts of sensi bloom A+B to reach 1.1e.c then top off with Big Bud until a reading of 1.6EC is reached. Week6:-Add 2.5mls per litre of Overdrive, then top off with equal parts of Sensi Bloom A+B until a reading of 1.6EC is reached. Week7:-Add 2.5mls per litre of Overdrive, then add equal parts of Sensi bloom A+B until a reading of 1.4EC is reached. ----------- Does this all make sense???

Hi All Starting to get back into this after a LONG time out and buying absolute rubbish to smoke! My memory is very hazy tbh so been watching a few Vids etc. I have roots just poking out of RRiot cubes and looking transplant into 3" cubes. What EC do i need, just looked at this video and he states 400PPM, is that not about 0.6? That seems high to me?? Plus his PH seems low, should it not be 5.8, should he not of soaked them for longer and let it 'level off' as we know RW increases PH. Also surely he should of trimmed them roots, would they not rot off at that length? I am SO looking forward to this guys, i've missed my own looked after and cared for smoke, i have some nice Gelato!! I also might add a tiny bit of Nitrozyme as well to the soak mix. Cheers guys and so glad to be back on here, i look forward to replies and the great chat, god i have MISSED this place......... VIDEO -

hi quick question i ec my water after adding nutes ,do i have to correct the ph also im growing in canna terra professional +

Do I need an EC pen as necessity? What is it for? Can someone point me towards a guide pls? I'm about to start my first coco gro...

What do you guys reckon is the best environment controller for hyperfans?

Hi, I'm starting my second DWC grow (5 plants in one big pot) and one of the things I hated was lifting the lid and checking the PH/EC (especially when the plants grew big). I was thinking to get a Hanna or Bluelab Guardian/combo meter type setup where I could leave the probes in continuously to make my life easy. I was wondering if the probes can be left entirely submerged (including some of the cable that goes back to the meter) or is it just the tip of the electrodes that can be submerged. I cant find any info on how these things are installed and would be grateful for any advice from someone who's is in know. Manufacturers always show the setup on the left, whilst I just want to dunk it in the drink like on the right....if you guys do it like the setup on the left, how do you ensure that only the end of the sensor is submerged (I always fill up to slightly different levels and also as the plants drink the levels lower). I don't feel brave enough to permanently install them by cutting holes in the side of the basin. +-------------------------------+ +-------------------------------------+ | | | | | | | | | METER | | METER | | | | | | | | | | | | | +-------------------------------+ +-------------------------------------+ \--- | | \- \ - | \ ----- | / | -----/ \ | \ -\ | / | -- / / \ | / | | | | / \ +----|-------+ / / | | | / | \ | | | / | | | \ / \--------------+----+--+----+-------------------------------------------|-----------------------------------| | | | \ / \ | | | / | | | \ | \ | | / / | | | | | \ | | / / | | | +---|-------+ / \ | | | | | | | | | | / \ | | +----+-+----+ / | | | | | | \ +--+ | | / | | | / \ | | | | | | / \ +-+ / | | |--------------------------------------------------------------------------------------/ Cheers

Afternoon everyone, I’m after some advice and wondering if anyone can help me out with R.O units and which is best to go for. My background e.c is 0.7 so water is terrible and I’m thinking it’s worth the investment now to be able to work with clean water and really give the plants a proper feeding instead of loads of unknown crap. My local hydro shop wants silly money for a unit so been looking online but there’s so many to choose from 3/4/5/6 stage which will be suitable? I’m guessing just a bog standard 3 stage will be fine but if anyone has experience with them I’d be grateful. Cheers

I’m currently on week 2 of flower with 6 stardawg girls. I’ve been using canna nutrients from the start and have been following the guide Almost exactly, I’m currently feeding at EC 1.7 but I’m reading that this is too high?? They seem to be happy but now I’m worried about bumping the EC up which is what the guide says to do as you get further into flower. Any tips or advise would be much appreciated

Morning all a quick question regarding ec I got a bluelab truncheon yesterday and tested my tap water it’s coming out at 0.7/0.8 now with it being so high when I start my dwc which will be in a oxypot Xl so 70litre res what should I be aiming for as a start point. My understanding is to stay on the lower end of the scale when it comes to feeding in dwc. I’m using AN Sensi Grow A+B and will be addingn some voodoo juice as I’ve read some good things about it. So Do I only mix feed in and make it up to say 0.9 which is only 0.1 of added grow or go upto 1.0 which still doesn’t seem a lot at only 0.2 of food. Cheers in advance

Hi Everyone, I am new here so firstly I would like to say hi to everyone and that I look forward to what I hope will be a long journey here on this forum. I have never grown before and I am currently prepping for my first, I will be germinating this weekend. I have just been calibrating my new pH & EC readers (both are Essentials) and getting base readings for our water. Here's where things are getting a little strange, we have an undersink reverse osmosis filter (we've had this for some time now as I don't want the tap water for obvious reasons, I have however replaced all the filters a few days ago to get the best of the best for my girls-to-be) and I know manufacturer (iSpring Water Systems) specification is that water pH should come out at 7.4, it came out at 8 which is fine for myself and will just have to use a lot of down, but the EC reading has come out at 0.8, which even as a virgin grower I know is waaaay higher than the majorities. I know that during filtration some ionised minerals are added (calcium, magnesium, sodium & potassium), but this has thrown me off completely as I now have no idea where I'm at with nutrients. My plan was to start the seedlings off with around 0.5-0.6 EC (assuming a base of 0.2) as I am growing in coco, so 0.8 is already higher than that without any nutes added. Should I just treat this as my base? Should I use normal tap water? I really am lost and have no idea how to even find the answer. Any help or general beginners advice would be hugely appreciated. I'm so excited to be joining this wonderful community and can't wait to progress, happy growing!

Hi all,, a couple of quick questions for you? 1, Does your EC have an effect on the temp of you res water? What i mean by this is, does the water in your res warm quicker/easier if the EC in your water is higher? 2, What temp is ideal for a res? Ive modded my wilma so the roots dont go into the res in the thought that i may be able to get away with slightly higher res temps if the roots are in it. Lights off im at 19c and lights on it climbs upto 22c. Ive tried everything to bring res temps down and really dont wanna have to buy a chiller. Thanks in advance...

Ok, the new problem... My PH is a bit low for my feed. So that is going to be adjusted. However, for those who asked in a previous thread what the PH and EC were, well I splashed out and bought myself a crissy prezzie of an EC and PH meter, they arrived today. I have tried el-cheap-o route, splashed out on a couple of middle of the range meters that were about the £35 mark each. Normally about £99 the pair, got then on deal via a trader that I have used several times for substantial purchases and got them both for £69.99. So these are not your £20 grow shop cheap as chips, ok for a grow meters. The PH meter was easy to set up, there is an option to set the alternative end standards of 4.0 and 10.0 on the PH scale, I just went with the Neutral PH 7 standard for now. The EC meter was pretty much same sort of deal, I happened to have bought, quite by accident a month or so back, EC28 buffer... Single button push calibration... Couldn't ask for more. OK now, those people asking what my water EC and PH is. This is a current state that IS GOING TO BE CORRECTED. Feed mix... PH 4.3 EC 1.3 Separate Water (for all uses, including adding more water to the pot when dry between feeds) PH 4.8 (Originally I set the PH to 7 for a baseline, was aiming for PH5 when PH was too high) EC 1.0 The water I used to water and other things like spraying was aimed at being PH 5 as I needed to drop the PH of the water in the pot as it was a bit high, the test paper system I used was pretty good guide and PH had risen to above 7. So now I can make the required changes to the current feed mix, readjust the water back to PH of 7.

Hi, Does anyone know of a good summary like a table of sorts maybe, that covers all the combinations of PH/EC behaviour, perhaps something like: EC PH PLANT IS DOING stable stable <chilling> down down <needs more nutes> etc etc I keep reading like tit-bits here and there but is there an authoritative reference? I'm in hydro if that makes any difference. Appreciate any info/links Thanks,

Right quick question tap water ec is 0.9 and i know people say start bloom at 1.2 ec but my plants been vegging a good 7 weeks from clone and feeding on ionic grow at ec of 2.1 that was including background of 0.9 so 1.2 worth of grow add to tap water ec , now they just starting 3rd week in flower so empty res and filled with water same ec 0.9 added bloom upto 1.9 should i go higher or will that be ok? Thanks barney
