Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

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.

Light burn or nutrient issues? Female?
Does this look like light burn and maybe a lack of nutrients? Also can someone confirm that she’s a female or is it too early? I am first timer and think I see her lady parts already.

Hi guys, I’ve noticed the leaves of 2 plants are curl upwards. I think overwatered, Day 9 I’ve watered two times (wrong) and after checking Day 8 too. At day 10 I've didnt watered, and today I've seen the soil dry, so I putted 100ml water. What do you think is causing this curl?

Spots and dry leaves.
Help! I don't know what's happening to my Q1. There are spots on the leaves and some of the leaves are really dry. I didn't do the defoliation and i didn't LST so the plant is just going all natural. I feed her nuts from ATAI.

Is the slight yellowing ad curling of these leaves ok or indicative of something?
Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between. I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

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 curling into bud
As sugar leaves send their nutes to the buds and start to curl/die, do I need to trim them off before the curled part reaches the buds? The fan leaves were an easy choice to trim...sugar leaves I’d have to trim the leaf rather than stem. Is that ok or necessary?

Leaves curl on upper new growth and mid but not lower.
I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.
