  1. Hello good folks of UK420, I'm having a spot of bother and can't determine if it is excess CalMag or light burn. Reason why I'm unsure is because I upped the CalMag by 0.1ml per L to resolve deficiency. I've come back to one lady with a few leaves on top going brown, tips curling up and the brown looks to be starting from the the edges working it's way in. Can still sort of see the veins of the leaf but not fully. Light were about 17 inch from plant at full wack so I'm also thinking that. Temps ect 26C 58% Growing in soil using BioBizz range Currently in veg so using only recommended doses of grow and calmag. Quite long veg time atm think i'm on weeks 7 Any help much appreciated. Cheers, CSG
  2. First ever grow, Hi all, so I have had issues with my 2 girls soil (John innes no2) was always wet, bad lights in beginning , recently found a gnat or 2 jumping and flying around, caught a couple now but doesn’t seem bad for now, recently been seeing yellow spots appearing on some leafs so had a look online found out it was something beginning with S forgotten the name as I’m here writing but I see a good treatment for it was neem oil which also helps with prevention from pests to your plant so have ordered some of that, for 3 to 4 weeks they were under bad lights I bought cheap from eBay, also ventilation wasn’t great as had no inside fan circulating air and was relying on air vent and extractor fan to help circulate, they are now 6 weeks and have had mars hydro ts1000 above them for couple weeks, and have a fan inside tent, also have a heater to go below pots to help dry out soil , my light does have a dimmer and is 150w at max, I have put them on max about 20 inches from plants for a week then after doing some reading of seen you don’t need them full blast at that height? They are both females (white hairs showing from a week or more now) am I at preflower stage? Or still veg, as the timing I guess should be in pre flower? But I know I’m in slow growth so not really sure where I stand, If anyone can have a look at my girls and let me know, what could be done or what I’m doing wrong or what could be going wrong, if my lights being at max is ok? And if so what height is best, a lot of new growth happening but not much in size in general, been also doing some lst last couple of weeks, I have also today done some snipping to some leaves that were to big and some that had yellow spots so it’s not as bushy as it was but still tiny, also due to plant being always wet at the bottom, I have not been feeding it properly, and only given 1ml of fishmix since week 3 to 6 and little root juice but only using about 300 to 400ml as bottom still wet (just trying to get some food to them to help them grow during slow growth of being to wet) not sure if I was making it worse or not , hard to find all the answers online. yesterday I added 1.5ml per litre fish mix and 1.5ml per litre of bloom so it was its first bloom feed at week 6 and the end of week 6 at that, as tomorrow is the start of week 7 from seed in soil, any tips/advice/help greatly appreciated thanks all

    Need help to know what is wrong with my plant, I’m totally new to this all and not sure ignoring iv been doing it right but I think there is a problem with it being a little light green, any questions or ideas please let me know all, thanks a lot in advance
  4. Had these three in a 15l tub for a couple of weeks with no issue. After a few hours in 25l buckets this happened... leaves very dry add brittle . This happened with my last crop but fixed itself out, suspect the same will happen here but still distressing. Went from one mil per litre veg and went to one and a half mil per litre flower feed. Strain is gorilla glue auto by fastbuds, any thoughts what this can be?
  5. Hi UK420ites I am hoping someone will be able to help me identify what is going on with this plant before it progresses further. The spots are a bit more orange to the naked eye. I am growing a couple of Blackberry Gum Autoflowers and a Gorilla Glue Auto. The plants are just standing in an insulated loft, not a grow tent, and I have a temperature controller which will turn on a heater if the space drops below 24C during lights on (target temperature of 26C), or 18C during lights off (target temperature of 20C). In practice the room is usually 24-25C during lights on, with a max so far around 27C, and 20-21 lights off, with a minimum reached of 18.7C. I have an air circulator 16” fan and small oscillating fan, which move the leaves but aren't pointed directly at the plants. I don't have extraction set up at the moment but have a filter and fan in the space sucking the air through. The loft hatch is open all but a few hours a night so there should be plenty air getting up there and I imagine I replenish the CO2 quite well with all the time I'm up there ogling them. Plants 2 x Seed stockers Blackberry Gum Auto started around 20 September 1 x Gorilla Glue Auto free seed from Herbies started around 30 September Lights 2x Mars Hydro SP3000 LED lights, now at just over 3 weeks since flowering they are 12-16 inches above canopy and near 100% power. 18h on / 6h off light cycle Environment 19-21 Lights off 24-27 Lights on Humidity 50-60% Nutrients I am using Growers Ark Coco Soft water Nutes. Currently feeding about 0.5ml/L Boost, 2.5ml Bloom A & B and Extra Traces, 2ml Root Tonic. My tap water has background 0.35EC and this solution is 1.35EC. Every couple of feeds I also add about 0.5ml/L Cal Mag and dial back the base nutrients accordingly, keeping EC to 1.3-1.4 (I have also strayed higher to 1.5-1.6EC but the plants looked a little overfed, so backed off again). I only do this as the instructions for the light say that more Cal Mag is needed than usual to grow well under LED. Plants are in 10L fabric pots and are fed twice a day to a good run off of 30% or so, there are no wild fluctuations in EC or PH with the run off. This problem is only showing on one plant on several leaves and the rest all look ok. I don't think calyx production has slowed but then again it always seems to take forever when you look at the plants 10 times a day haha. I think maybe I went for too many firsts with these (First time using LED, first autoflowers indoors, first time doing LST, first use of Growers Ark nutes) and am suffering from information overload from the amount of reading I've done, so maybe I am missing something obvious? Sorry for the essay, thanks in advance for any help you can give me, if I've missed anything off please just ask.
  6. I really dont know what I'm doing wrong here. Temp is at 24oC-26oC approx. Humidity is pretty high. Water coco coir autoflower feminised full spectrum LED lights air circulation I'm not sure what else you need to know to help but please ask. Leaves are kinda crispy but it's being watered. It also hasnt grown any in about 2 weeks. It's just stopped.
  7. Hi all, So as you can see, I'm growing 3 plants. They are 27 days old and 2 are doing well and one isn't. My camera is crap so apologies for that. All 3 plants are White Thunder although I have suspicions that i got seeds mixed up and the little one may be Dr Widow. I started with 4 plants from seed and then picked the best looking 3. EC is currently 750 ppm (500 scale) and I was feeding them 3 x per day for 15 minutes via my wilma system, in clay pebbles, 18 litre pots. Currently under 400 watt but am thinking of turning up to 600 soon (dimmable ballast). At first I thought the small plant was in a draft so I moved it to the other corner but it hasn't improved. Then I thought it may be over watered so I went down to 2 x feeding per day and I've moved the drippers right away from the little plant. The other 2 are green and healthy, the poorly one has yellow lower leaves, although it has some healthy looking new growth. is it just a dud or can I bring it back to life. all advice welcome. I'm using Dutch Pro hydro and vita link root stim, in a 1.2 by 1.2 by 2m tent . Whatever i'm doing, 2 of the plants like it!!! it's just this little bugger that isn't having a good time. help please!!

    Hi folks I was wondering if anyone could diagnose what is going on to the leaves in the pictures. The older lower and middle fan leaves are yellowing and have blotches on them, Magnesium Def?? Plant is a NL auto, at week 9, outdoor poly tunnel grow in soil. I've been feeding Biobizz nutes, Fish Mix and Bloom, slowly building the Bloom to 3ml per litre, Fish Mix at 1ml per litre throughout grow. I'm in Scotland so my temps aren't the best, has dropped quite low to around 8 degrees C during some nights. My PH going in has been between 6.4 and 6.8, and the run off seems to be the same, so I don't think it's a PH issue. Any help and advice welcome please. Thanks
  9. Hi everyone. I've been holding off posting anything on this for a few days while waiting to see whether an issue with my plant was due to over watering or something simple. I'm thinking now that it's probably something more complex. An overview of my set up is as follows: Seeds - California Snow Autoflowers Growing area - Approximately 1200mm x 1200mm area curtained off in an enclosed lean to at the back of my house. The area is lined with heavy black plastic refuse sacks and then space blankets for reflectivity Environment - Between 21 and 29 celcius, 40-50% RH. No additional heat or fan being used Growing Medium - Coco coir (flushed and buffered with cal mag over a 36 hour period) with 20% perlite Light - Kingbo 150w LED full spectrum UFO (approx 6" from the plant). Light is on 24 hours Nutes used - Only Biobizz Biogrow so far Before I start I just want to say that budget is extremely tight now as I just found out last week that I will be losing my job at the end of July so hopefully I can come up with a simple and low cost remedy - please bear this in mind if you can! The photos below are from this morning which will be day 25. Basically, all seemed well and she was growing fine up until around day 22 when I noticed that the lower leaves were yellowing a bit. For the first week I was watering tiny amounts around the base with no nutes and in week 2 I started adding 1ml per litre of Biogrow, giving her 500ml per day. The run off PH has remained steady at around 6 although I can't give an exact figure as I'm using paper PH strips. As I wasn't seeing any signs of over watering I continued with this until I spotted the yellow tint to the lower leaves. I haven't watered now since day 22 and the top surface of the coco still seems a bit damp to the touch which seems odd given the amount of water I've given her. She's currently 5 1/4" (around 135mm) tall and the top of the plant is around 1" (25mm) below the rim of the pot. I realise now that I've probably under filled the pot, hence lining it with silver foil to try and reflect some of the light to the lower leaves and bud sites. I realise that my LED lamp is a bit underpowered and to try and help things along I've been leaving her outside on sunny days to try and soak up some natural sunlight. I do have 5 additional full spectrum LED strips which can be daisy chained which may help in adding some more light but to be honest I'm not sure what benefit there will be (photos added below. Anyway - I hope that there's enough info here to allow some of you guys to take a look and advise but if there's anything else you need that may help please do let me know. Thanks in advance

  15. A question about my plant: Some of the leaves around the middle of the plant are looking a tad yellow. The top leaves are curling downward. Just checking, is this OK or do I have a problem? Ta.

  20. Hey guys I’m growing some white diesel haze, I’ve got 2 of these going , one is a lot bigger than the other , I think this is due to me over watering the smaller one when it was young... any way I’ve noticed over the last couple of days I’ve started getting rusty looking sugar leaves on the bigger one. I don’t think it’s light intensity as the “smaller” one is actually taller and that ones fine.... any other ideas what it could be ? so info 1x1x2m tent coco , hand watered Dutch pro auto flower nutes 2ml/L Dutch pro explode 1ml/L lights : Spider Farmer SF2000 (x2) on 18/6 pH is good ec 1.2-1.3 I’ve noticed it’s spreading across the plant, it started with the main kola now it’s on pretty much all of them. im on week 5 of flower with While Label Seeds saying they take 5-7 weeks , so I’m assuming it’ll take a little longer than what they say . any advice , things to consider ?

  22. Hey guys, i'm running into a bit of a problem , or so i think. First time growing autos. I have 2 Auto Diesel Haze growing. One has started to be real droopy with purple veins on the leaves and the leaf stems. The main stems are still green. The other one has green leaves , so i'm wondering where i'm going wrong. At first I thought i was over watering as I did start to get some fungus Gnats so i've been letting it dry out a little more before watering but the droop continues Set Up 1x1x2m tent Lights 2 x SpiderFarmer SF2000s 18/6 Medium : Coco Nutrients : Dutch Pro Auto Bloom A/B 30ml/10L , DP Explode 10ml/10L Pot Size : 20L watering everyday/every other day depending on how dry the soil is ..... average watering 5Ltrs Sorry if i've left anything out , i'm really stuff here ... oh heres some photos
  23. Hi all new here and new to growing! This is my first plant and so far Ive been getting by with just reading what I can online. As you can see I'm doing something wrong and I'm stuck as I have no one who can take a look at it for me so just after a little help. Im using the full bio bizz range and using half the amount they say. It's in bio bizz light mix, would really appreciate any help Cheers P
  24. 3 week into veg I think I gave them nute burn but I have flushed them out and they came back and started looking good. I then left them for 3 days once flushed and then gave them. 10ml of A and B Dutch pro and 5ml or take root in a 20 litre mix. 2 1 litre jugs. The day after they ended up going like this. The pots seem a little heavy. So don't know if they been overwatered or they gone back to being nute damaged? Temp around 24 to 28 when lights on around 17 when lights off. What shall I do. Will they get better is it worth carrying on with them?
  25. Hey guys I need some advice please. I'm growing pineapple express auto, i've ran into problems along the way due to root rot (from high water temps i think), i soaked the roots in H202 6% at 1.5ml/liter for a few days and then i removed all the bad roots by washing the roots off under the tap. the roots submerged under water seem okay now but the roots inside the pot are still bad and i think the root rot is still there and affecting the plant, the leaves keep getting brown spots and i keep picking the branches off to find the next day there's more infected leaves. I'm worried the brown spots will spread to the buds and i read that smoking it could make you sick? i was wondering if i should start flushing now and harvest early to prevent this? can someone please try diagnose whats wrong with the photos i linked below and give some advice on what to do. someone please help! thank you. photos of the buds and leaves - http://www.uk420.com/boards/index.php?/gallery/album/16696-sick-plant-flush-and-harvest-early/ info about my grow set up 18 liter pot, 600w LED veg+bloom light 1-2 foot away from the plant, ph between 5.6-6.1 at all times, room temp 21-24c, water temp i try to keep around 16-18c (but it does go up to 22c while im at work which is why i think its gotten root rot) i've been dosing 0.2m/liter of pythoff since i got root rot and havent stopped adding it to the nuterients, ppm around 750-950, air ventilation aint the best as i need new fans and the carbon filter kinda sucks need a new one, plant is roughly 3 months old. if you need anymore information please comment below.
