Looks like it could be afew things. Heat stress could be causing the curling. The brow spots look like a calcium deficiency to me. Happened to me when my ph was off. I second making sure your calibrated. And also make sure your ph is on point when feeding. Also is your hand feeling uncomfortable under the light? It could be to close to the plant but hard to tell in the pictures.
Your issue I most likely calcium deficiency /Ph issue.

Hello
Any chance you've recalibrated your ph pen lately just to make sure its running accurately?
Otherwise those high powered lights will cause curling(especially the curl upwards) and discoloration if they're putting a lot of heat out and getting a tad close to the plants.

High there!
Small tips :
Close your light when you take picture, the coloration make troubleshooting very hard.
Look like heat stress but can't be sure of anythin because everythin is orange :D

Deficiency/toxicity?Hi, back again 😂 so the canooing has stopped on some plants but still present in some. I've also noticed the leaves to look a little off, is this the start of something I need to fix? They look pretty healthy other than that. The photos are of different plants. Thanks in advance

Unhappy seedlingSee the photo of one of my seedlings that appears quite unhappy. My guess is light/heat stress, BUT I have 8 other seedlings growing right next to it, under the same grow light, in the same soil, that are doing just fine. See 2nd photo of another of the same strain that's fine.

Upward curling leavesYesterday applied heating mat bcs temp was dropping to 14C nights. Now it stays 30C allday with RH 30%. I have found my seedlings looking like this morning. Leaves look dry. Could this be the excessive heat shock? Or soil dried up quick? What should I do? Water? Raise RH? How?
