Is there enough light?
Thirsty_Grower
started grow question 25d ago
If the upper leaves start to curl upward slightly into a “taco” shape, does that mean the light level is already at the upper limit and I definitely shouldn’t increase it?

Has anyone else heard of using epsom salt with gallon of water for magnesium and sulfur issues? I'm told you can water them or spray them during lights out. I've had some issues before with magnesium due to soil pH recommended by maker didn't follow it I later corrected it pH

Upward curl
Hi Breeders, Elizabeth is growing well, but the bigger leaves are curling up at the edges. I already increased lamp hight and lowered to 18/6. Is it air humidity? Or too much water?

Light Stress
Had to move my plants to a new space and under a better light, can see taco type appearance to leaves, I'm assuming this is due to light stress? I've lowered the plants and also turned the light down a little until I know what is going on.

Leaves folding in
Was wondering why new leaves on my new clone are folding? I’m not very experienced in growing, and I’m just getting it started so I can move it outdoors in the spring. I have a 300W pink grow light (idk any specs or even brand) it’s on 18/6 hour light cycle

Everything seems to be OK except one thing (week 3). I thought using the greenhouses at night made this, but it doesn't. When I check the plants early in the morning, their leaves are slightly curled upwards, just along the edges. As the hours go by the leaves flatten. Any clue?

Leaves are looking a bit strange.
Leaves looking sick hope its not root rot, i changed the light but only from 25% q5 to 50% evo 3 maybe it was a bit too close. I tried closer to prevent them from growing more in hight.

Weird looking seedlings? (uploaded vid)
My seedlings, especially Seedling 1, look kinda weird to me. Seedling 1 appears to have some weird yellow spots here and there and the leaves look cut? They just look really weird and not like normal cannabis leaves, both seedlings have their leaves going up at the corners.
