Why are the sides curling up? Question not about them pointing down but only about the sides curling up and very small brown points
What is this? Sides r curling up. Day temp didn't get over 23 degrees night temp is +- 12 so I don't think she got too hot. Points bit yellow Saw this yesterday evening too, today at 1 plant a little bit. They're probably pointing down because of the low night temp so that's ok

Week 4 Seedling is wilting/curling! (See Pics) Hard and dark cripsy edges on all growth. I dropped two fan leaves incase it was mold. Looks a tiny bit better the next day after taking off the humidity dome that was on for about 24 hours before noticing the curl.

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Otherwise healthy leaf curling in on itself at top of plant
Anything to be concerned about? This is a plant that has had a history of yellowing leaves due to I think nutrient deficiency. New leaves are coming in light/dark green. Maybe caused by being too close to the lights? (It is my shortest plant with about 1 ft distance)

Will these leave deformities disappear or am I screwed?
Hi there, I recently started a new grow and the leaves seem a bit odd. Do you think the plant will get a hold of itself or not? I myself have opted to wait a couple more days but if things haven't gotten much better in a few days I might restart.

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

Curling and twisting leaves (main bud polyploid?)
Hi cannafam, the leaves of this Blue Amnesia Auto are turning, twisting and curling up a bit.. Anyone know if overwatering might be the problem? Have been watering (and feeding) her as much and as regularly as the others (no prob there), but she is a bit smaller and skinnier
