Cannabis Troubleshooting

Hi First time grower here. Built a 1m by 1m cupboard. Sprouted 16 seedlings and put them in small pots with coco coir. I think I overwatered them as most of them have died. Using an Optic Sun 2 LED 210W - Not a huge light but should be ok for small size I have? My question is how often should I water seedlings for their first week or so when they are in coir. Water seems to drain through the coir pretty well. I see others saying only water every 2 days or so but they are talking about organic soil. Is it the same for coir? I was watering once a day. Also I think my light was too far away as the sprouts were quite leggy. I may invest in a CFL fluoro and try a…

Greetings, I have a rather discoloured and sickly looking Amnesia Haze auto seedling and not sure what to do. Please see photo below. I’ve been feeding all 5 of my plants 2ml per litre of Advanced Nutrients Sensi Coco and also B52 in coco coir/vermiculite medium in solo cups. The other plants still look healthy and a even green colour through out. This Amnesia doesn’t seem to be fairing so well. Does it look like nutrient burn? Or over watering? The others are bigger 3rd&4th nodes up, so the prob can handle the nutrients better? The coco drains really well and has plenty aeration from what I’ve learnt. Appreciate your advice!

This plant is around 25 days old, Yes i know its small, there were a lot of bad conditions when this was growing which I'm sure has stunted it but it's showing more growth than ever now. My general concern is both the tips of the leaves and the weird black/grey blotches that you can see on some of the leaves This has only popped up recently (last night to be exact) and I wanted to get some comments from you all, as I know for a fact some of you would've had seen this before. Could it be mold, mildew, a pest of some sort? I really have no idea what it could be. , Thanks

hi all first timer here growing in perlite with a 70x70x160cm / 27x27x63 inch tent using a OPTIC 2 LED 205 Watt COB LED GROW LIGHT. This is the third week veg now and i had no issues up until the other day i noticed a black metallic "paint" type substance on the plant leaves which after researching turned out to possibly be thrips? I'm not really 100% sure. To be safe i sprayed them with a Pyrethrum based insect spray but i stupidly did this during lights on rather than waiting until they were going to sleep. if it matters I'm using general hydroponics flora trio nutrient with gh calimagic @ 75% strength without any signs of burning or slow growth. everything se…

Hi all, My ambient humidity is going up in the area... Due to there not being much room in the grow room, I can't fit in a dehumidifier. I want to dry my plant out as quick as possible now. Is anyone using kitty litter in bowls or dessicant from woolies. etc? I have read that it works in some places, others not. Any local results? Thanks in advance!

Hi all, First time poster/first time grower, but long time lurker. I'm posting now because I'm really stumped with whats wrong, so I'm hoping that you guys will be able to assist and help me ID these problems. My setup: ------------ Indoor Soil (Canna Terra w/20% perlite) Water every day, nute feed (1/2 Lucas formula + cal/mag) every 2nd day PH: 6 going in, about 7 coming out (approximately) 20 degrees temp, 50% humidity 450w LED 4" extract fan through carbon filter Growing: --------------- 2 x OG Kush (autoflower) - 4 weeks 2 x Jack Herer (photo-period) - 2 months * Yes - I know its weird mixing an auto and a photo-period. I will be passing the Jack on to a frien…

Hi all I am new to this forum and this is my first request for help the plant in picture was doing fine until a few days ago when the older leaves started yellowing and a purple tinge started to appear im running flora early bloom at 1200.

So this is a fem seed I bought... The shell got stuck on pretty bad and dried out a bit, doing some pretty serious? damage to the cotyledons... Should I even bother keeping on growing, or throw out and start again. I'll trust your experience! I only want to have 1 plant at a time for legal reasons, so if this one is a complete waste of time and resources I would rather cut it now. But also don't have a plethora of seeds... at this rate I should have bought 20 seeds at the hope of one good plant! hehe This picture was from 4 days ago... It now has a few seemingly healthy true leaves. This is the best photo I could take... basically the tips of the cotyledons are gone…

Can anyone tell me what is causing this? its on the older leaves and the new ones are green and dont seem to be affected. Not sure what it could be??

I’ve recently germinated in peat pellets and then transferred to a soil vermiculite, perlite mixture. The seedlings are just now showing signs of over watering. While the soil mixture has good aeration and very dry before watering I only just realised the transfered peat pellets seems to stay wet. Am I best off just watering around the edges of the pots and avoid the peat pellet, Or should I bottom water by putting pot in saucer when dry. Any ideas. Anyone else ever had this problem? They are 2 weeks since germination.
