Upward curl
GrischaBXL
started grow question 5y ago
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?

When leaves curl (taco) it's usually a sign of heat/light stress.

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

Looking droopy/yellow due to light burn?
Looking like light burn (most intense from the top) and maybe overwatering? I am trying Nectar for the Gods #4 soil for the first time, and I just put it in a grow bag and put the clones in it. Unsure if I was supposed to prep somehow beforehand.

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

leaves dry and curling up
Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches
