Hi all, Can anyone give me some clear advice on what seems to be the trouble with these young plants? I have of course researched possible causes but there is nothing definitive i.e. it's this, not that! I know it will be watering/nutes/heat (clearly it's very hot right now!) Sorry about the image quality, shot under HPS lamp! I can get better if needed. The issue is yellowing ends of lower leaves with a small amount if creep to a couple of upper leaves. Background Strain: Fat Banana Autoflowering Age of plants: 4 weeks grown directly in media, so no transplanting Media: British Organic Bio Mix (85%), Canna Coco (10%) plus perlite Nutes: Dutch Pro for Autoflower/Hardwater/Soil. I'm taking it very easy on the nutes as the plants are autoflower and I'm following the Dutch Pro watering/feeding schedule although this is concerning me most, so any advice here would be appreciated Light: HPS 400w about 18-20 inches from plants Air: 2 fans for circulation but not pointed directly at plants I look forward to hearing your thoughts, thank you iamnormal

I don't know where to start. As most people know, money is fucking tight. I'm giving some very serious thoughts on using Chempak simply because I can't afford dedicated nutes. So, say for example, Canna might offer their A & B at something like 5/6/7 (a guess, but low numbers) and Chempak have it at 20/20/20 (I know there's a range) - how do I balance out the high numbers into lower numbers more suited to frequent fertigation for cannabis plants *please *? I think there might have been an answer here before but I just couldn't understand it. It didn't seem to be as simple as just diluting it but I just wasn't sure. Thanks in advance. Stay safe.

Hey guys, I put these photos on my diary page but I thought I would add them here also as there is defo something going on. I had an issue with extraction so temps went up as did root temps and humidity dropped. I have since fixed that but I’m not sure what’s going on here. I am just about to start in external nute regime (I’m on week 6) as the nutes in the GK Soil are at the end of their life. Does anyone have any idea what’s happening here? Thanks for any advice and suggestions, all are welcome. Thanks.

Hello everyone, I am running a 6 bucket rdwc with cyco nutrients, using bloom a+b, swell, b1, sugar rush, supastiky, and Dr. Repair at dosages suggested by Cyco dwc calculator. I'm noot using clones and some plants have taken better to the system than others. I'm about week 5 but also previously i've noticed the PH dropping from 5.8 to usually 4.2 overnight and EC slightly rising. Any ideas on the reason behind the plummet? Thanks

Hi guys done a few grows in soil but watering is becoming an issue as i can be away a few days at a time. Getting a wilma and have decided on clay pebbles. Few questions how do you start a seed in clay pebbles? Rockwool ? Root riot cubes? Or something else? next question heard good things about ionic nutrients so have decided on them can i use silver bullets with this? How often should i set feed timer Whats ideal ph and ec for this system thanks in advance guys dont want to muck it up .

Hi I need some advice on harvest please I grow in Coco using Canna nutes wich I stopped feeding a couple weeks ago, The two plants have been in flower for 8 weeks now and are really looking good. They where on 2ml A+B, 2ml Rhizo, 2ml Zym, 2ml Boost, all per 1L they did have some pk through weeks 5 and 6 with week 5 being a slow build up and 6 a full 1ml feed. I have started flushing my two plants Special Kush(SK) and Royal Domina(RD) around 11 days ago now and the leaves dont seem to be going that yellow at all. My two plants had a bigger flush 5 days ago in the bathtub where I put a bunch of ph water through each pot till the runoff was clear. Only a handful of leaves have started to yellow up and I am not sure if I should continue flushing for some more time or if its okay to harvest. I know for sure SK needs a week or so extra as I can physcially tell with the swelling the pistils and the trichomes are more clear on SK so not as mature. As for RD she is looking ready, buds look very full and swolen even the lower ones have swolen pretty nice the pistils seem mature and most importantly the trichomes are a really good cloudy covering across the plant with 10-15% amber. Is it okay to chop RD based on her being very filled out and her trichomes being a good cloudy coverage with amber mix or would it be adviseable to flush more allowing the leaves to yellow up ? Here is Royal Domina(RD) The one im looking to chop now, you can see near the back of the plant only the one small leaf starting to yellow. Here is Special Kush(SK) I am looking to give her a bit longer anyway due to her trichomes not yet being milky or amber they are mostly still clear but you can see the nug I have my hand behind the tips of the fan leaves are the only signs of yellowing on this plant.

Morning people. It's been three days since my seedling sprouted and it's looking better than ever. Anyway, there seems to be so much conflict on when you should feed seedlings in coco. I've got the whole CANNA coco range apart from CANNA Canazym. Some people say to feed after two weeks of sprouting as the seed has enough nutrients... Some say to give a light feed from the beginning... Which one is it? I'm using canna coco natural... Any coco experts that can help me?

Hi guys. So I'm 44 days from seed with a Zkittles Auto from Seedsman and it started showing some deficiency, I'm pretty sure its sulphur, anyway, I did the usual go to first off and checked the PH of the runoff. Now I'm very particular about my PH when watering and I always have it between 6.4 and 6.8, and its planted in Bio Bizz All Mix which as far as I understand is neutral at 7.0, and i was using Bio Bizz Grow and Bloom nutes which are pretty stable at around 6.5, which is their recommended anyway, so when I collected and check the runoff and found it was down at 5.2-5.3 I was seriously confused. Any ideas what would shift the PH that dramatically when I know 100% im OCD when it comes to these plants and watering? Cheers guys.

hi guys just looking to hear from anyone growing in deep water culture, about the additives you put in your water, any setup tips and just any tips in general, basically just looking for as much info as possible, if you could try and keep it simple for my baked brain that would be great, thanks in advance

Hello all hope everyone’s doing well! has anyone had any experience with Plagron nutes? Especially green sensation? I tried mills nutes but there was too many, then now I’ve got bits of everything and I’d rather just a few bottles of the same to be honest and Plagron is ticking the boxes. Just what to know if anyone’s had good or bad experiences with it at all

Howdy folks. Just looking for some advice on feeding for my 3 autos. They are from Paradise Seeds, Strains are: Wappa, Whiteberry and Vertigo. Have them each in 11 litre pots in soil (had John Innes in it). They have reached the 3 week mark now and I have some Terra Flores I'd like feed them with. First time growing autos, but I am growing them in a kind of sun room/conservatory. But I put them outside when the sun is out (they've really thrived with the great weather here in Ireland the last week). Would anyone know roughly, how much Terras Flores to use with how much water? Complete noob here and worried about damaging them. From what I have read, less is more. Start ut with very little and see how they react and then up the feed from that point on. Have a rough estimate to start out on 1ml Terras Flores with 2litres of water for the first week of feed, about twice a week. Then up it by 0.5ml next week. Does this make sense or m I talking out my ass? Any help or tips would be greatly appreciated

Howdy peoples, I'm brand new here, and to these operations, so would be grateful for any and all help in solving some questions. I've planted mine in Canna Terra Professional Plus, and just started the feeds with Rhizotonic and Canna Coco A + B. Looking around I see so many different opinions on whether theses are the correct nutes for this medium (though it kinda says so on the bag). Also, is it cool to mix all 3 into the same feed? And how long does a feed mix last? i.e. I mixed 50L in a tub, but only use 10L at a time, is this bad practice, should I just do 10L each time, or will the feed mixture last? Thank you in advance for any help :-)

Hi all, I fucked up and ordered Bloom nutes for soil (Dutch Pro) and I needed hydro. I can't return them as they're open as I didn't notice until I was about to use it . From what I can see on the Dutch pro website, it's just not as strong. What do you all think? can I use it or have I wasted £50? I'm using a Wilma System The Hydro nutes: 4.9%NO3 5.9%K2O 1.3%SO 0.006%B 0.015%Mn 0.4%NH4 3.7%CaO 0.4%Na2O 0.002%Cu 0.002%Mo 2.1%P2O5 1.4%MgO 0.3%CI 0.021%Fe 0.006%Zn N-P-K 5-2-6 TOTAL The Soil nutes: 4.4%NO3 5.5%K2O 1.1%SO 0.006%B 0.015%Mn 0.4%NH4 3.7%CaO 0.2%Na2O 0.002%Cu 0.002%Mo 1.7%P2O5 1.0%MgO 0.2%CI 0.013%Fe 0.004%Zn

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 guys, So I'm just about to start a new grow / mummy hunt and my supplies are in need of restocking. Previously I've used various boost products, and I've done OK. My question is - would I have done just as OK if I save my money and not use any boost at all? Maybe replace using boost with something organic like molasses? What are peoples thoughts on using boosts, are they any good, can/do I get better or more ganga? I've read a good few dairies on here from folks who've grown a lot longer than I, using minimal nutes & adds with awesum results. I usually use these during a grow...do I need to or can I drop some? If so, why or why not? Base stuff Rooting stuff Enzyme stuff PK stuff Boost stuff Silica stuff Open for all thoughts, lets try and keep this as objective as we can where possible tho.

anyones used remo nutes or genesis would love to know your experience with these notes

okay guys sotoday whilst feeding my girls i noticed 2 buds had yellowed in the middle. the beast from the east has been over and iv had my ballast on 660. the plants have stretched even more and im guessing this pheno is slighlty more sensitive than its sisters. is this light, nutes, bad ventilation ? iv rearranged and retucked some buds through the scrog again, im just hping to get reasurrence. so what do you guys think light or heat burn ? got a normal bud below and here we have the estranged bud. obviously im a novice this could be simple and im overthinking. but i just want reassuring theyre not herming out or anything any response would be appreciated guys

Hi guys have been using biobizz with soil for a few years now and have had a fair bit of good success with it but since ive moved it doesnt seem to be working as well as it was not sure if it the difference in the tap water or not ph at my new place is 6.2 from the tap i cnt remember what it was at my old place but im sure it was around the 7 mark can anybody recommend a good range of nutes that will be good with my standard tap water an not have to worry about a mag probs?? Cheers in advance

Hello folks. My grow is starting this week!! As excited as I am im also nervous.. Just need some general guidance really. Gonna be growing in coco and I want to add perlite? What ratios should I be using? The kit I bought came with clay balls should I be using them? I was hoping also to water every other day if I can. Also I don't really know about feeding and nutrients. I have canna a and b and the flower boost. As you can see im a super amatuer but I want the best results possible any and all advice welcome! Cheers in advance folk

Hey, lurking for a while but this is my first post! Recently invested in an 8-pot Autopot system with a 100ltr reservoir, will be growing in a 70/30 coco/perlite mix and was looking for some advice on which brand of nutrients to use. I've been eyeing up the Cyco Platinum range or the Canna Coco nutes, but I'm aware Canna also have Hydro nutes. Anyone have any advice or recommendations regarding these or any other nutes? If anyone has grown in Autopots with coco before would definately appreciate you chipping in your 2 cents. Open to all ideas. Thanks guys

Good morning guys.. Just a quick one.. When i water my plants with a feed if the plants doesnt take all te nutes up and some of the nutes are left in the coco then next time if i feed with plain phd water will that reactive the nutes that are in the coco from the feed before for the plant to take them up? Or will the nutes just stay in the coco and create salt build up?

Hello guys, im about three weeks off my first harvest, its been ok but I think I can do alot better. Firstly id like to understand abit more about the diffrent ways people grow then id like to pick witch way is best for me, im a complete novice still. Fir my first grow Iv used a barky mix from homebase( I want to use something better for my next grow possibly soil) Iv used five gallon pots( cheap things frm Bnms bulky and I forgot to put drainage holes in) definitely want some better pots for next grow. As for nutes Iv been useing old timer Bloom for flowering and I used some pound lqnd nutes for veg( I know I can do better than pound land nutes)reading through alot of topics im seeing alot of this soil need to be used in these pots with this feed and thats that, so im not even sure if the nutes I have old timer is doing anything for the kinds of barky soil mix im useing or whether my pots are good enough. Im currently looking at biobizz all mix/light mix on ebay, if I brouht some what nutes would I need what are the best pots to buy? Iv seen some air pots for about a fiver for one 10l is that good, do I want air pots? This can all be a little confusing, and some of you might think these questions are stupid but this is something I wanna do for the rest of my life so I wanna do it right. Peace and one love everyone hope your days been good, any and all feed back is very much welcoming.

I am new to the forum and enjoy reading the opinions of so many people. I have a fair few years of growing under my belt and probably over 50 grows since 1985 when I first started. It might be more like 100... I digress! In the old days we butchered 400 watt warehouse lights and made reflectors out of any old sheet metal, normally from the skip of a local firm. There wasn't any Coco but there was soil and basic feeds from AG Shield, Pickerings or Comptons Agriculture were Pot Nitrate, Mono KP, Epsom Salts and Lawn Feed were made into stock solution etc. We used to veg for a size of about 24 inches and flower until the pistils went brown, the smoke was never flushed and it was strong stuff the old original Afghan strains we later called Skunk 1 and 2, but until about 1990 we could only get seeds out of VIZ, the comic for adults! I remember smuggling 50 JH seeds shoplifted by a 'mate' from Amsterdam, i was sick with anxiety all the way home on that horrible ferry to Hull, I never realised it was legal to buy the seeds! Most plants produced around 5 ounces with nothing more than topping and feeding your own brews out of a tomato growing book or indeed anywhere you could get a recipe from. Most farm supplies had brochures, leaflets or instructions as to the use of most chemicals, so a mixture in pounds and ounces got weighed out on mums kitchen scales of Pot Nitrate, MKP, Lawn Iron, Epsom Salts, Horse mineral supplement and Molasses, it kind of worked! The leaves were our guide as we couldn't get or we wasn't aware of EC meters until 1990? We also discovered Canna A-B around 1990 and bloom boosting with MKP and the good old Corn Syrup fed to pigs, bloody good stuff that was! Anyway the leaves yellowed, curled up, curved, swerved, spotted, dulled and went every colour from red to dark purple before harvest but the smoke was knock out and yielded well, certainly 5 ounce as an average. These days if I try hard and go 30 inch in veg with a commercial strain like BB/NL or WW then its near to 8-9 but as a normal grow in Coco with Blue its 4-6 and yeah its stinkier but commercials like the old NL were better for you're stealth as they were low odour! I have an old Polaroid somewhere (that was a photograph that developed inside a liquid folder after popping out of your dads camera for the babies among you) depicting my prize 4 plants under a single 400 with a fan the size of a 747 turbine ducted up and out of our mums old cellar! I hope I can find it because those babies were pretty impressive tops! So today we spend £35 on a base feed like Canna Coco A/B which is fair enough for 5 litres but for the 4 plant man buying a litre its £15!!! The Canna base range of Coco, Soil and Hydro are the best available in my opinion. I remember it when it was clear and contained no iron or copper sulphate. Then we have the 'additives' pro bloom booster, micros, silicate, hammerhead, bud blood, bio boost, top gun, bud candy, terpinator, resinator, pk13/14, cannazyme, zone, rhizotonic.... blimey we should be growing our own Penicillin! I am not an addict for the additives but I do love to open a bottle in my local shop of something new and miraculous that promises me big, oily, tasty buds, mega lush growth and stems the thickness of Arnies forearm... but my question is "Do they work? Do some work? Do none of them work? Or do the nutrient companies just cash in our desire for better product and our gullible trusting nature... We aren't wary of the advertisers or videos on You Tube because anyone who dares to comment with "I used it and its rubbish" gets removed! Or at least mine did... This is a little bit tongue in cheek and obviously we are all adults with a brain and can choose whether we go spend £20 on a bottle of water that contains a secret ingredient we can't be enlightened with... How did Advanced Nutrients retain their credibility when the 0-50-30 Bloom Booster Pro got dropped because people cottoned on to the fact it was just MKP, Iron Chelate mixed with some copper sulphate and then ground to a finer powder to look and smell amazing! We are now told that KP ratio should be 1-2 not 2-1 but wouldn't a big nute company like AN have known this for years? Of course they would because researching the needs of a crop is easy for a fertiliser manufacturer. Can you imagine YARA turning round after 15 years of selling the Vitamax mixture of 20-10-20 to Potato farmers saying "oh sorry chaps but actually we've got that wrong its now changed to 20-20-10 but don't worry you've only lost about 20 ton of spuds" I think you get the picture... Also can someone tell me the significance of PK 13/14 if the PK ideal is 1-2? It just so happens that the ratio of NPK showing 0-1-2 is none existent in commercial fertiliser so that includes 0-10-20 or 0-20-40 etc and why? Well because some turd at a nutrient company saw we couldn't go out and buy it from the local agricultural suppliers at £30 for a 25 kilo sack so decided to make their own and then poison our brains with a new regime of 0-1-2 as the miracle formula!!! Or am I just getting cynical in my old age...
