Kind of looks like it could be both light stress and calcium issue.

Leaf discoloration and curling
I’m not sure what’s wrong but all my other plants are fine. It’s in pearlite and peat moss and I’ve been watering with ph balanced water. I did use a very little bit of half strength dyna grow but I only did a little squirt.

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.

I was making reckless mistake for exposing the plant into too much light causing burnt tips during seedling stage going through day 5. Light intensity was at 75% with the height of 28 inches.Any recommend on recovering these baby ASAP ?

What’s causing my leafs to curl?
Leafs are curling inward on new growth. It’s not exclusive to the tops. It’s only 2/4 plants. It’s still growing fine as it’s my tallest and biggest plants. I’ve adjusted my light down to 2/10 as my first fix and moved the fans around. Any suggestions?

Leaves curling up and Tips drying out (Day38)
Not sure whats going on? Heat stress, Thrip related, too little nutes or water? Noticed a slight curling yesterday and guessed on thirst since watering was delayed and then gave just half dose. Also heatwave going on right now. Nutes are at very low levels..

Dear experts, could you help me ascertain whether the 4th and 5th picture on my Week4 diary is really heat stress? The only reason I think that is because of that slight cupping/curling of the leaf edges. Might there be other problems that could cause this?
