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.

Overwatering?Can anyone confirm that this curling up is due to overwatering? I don't see any yellow leaves that would indicate overheating. But I read it could also be a nitrogen defeciency?

Hulkberry turning dry and leafs are bending upHulk berry auto flower leaves turning dry.
Hey, my Hulkberry is not doing so good, I assume this is due to overfeeding it with fertilizer. Right now I just flushed the plant with 6.1 pH water and I'm waiting to see if it helps. What more can I do?

Why the canoe effect on Fan leafCan anybody help me ID what is happening to these Fan leaves, at the top of my Black Willie.
Leaf temp is 1c cooler than the room. Leaf 22c, room 23c, rh%55, lite distance 45cm.
The leaf is showing that its folding like a canoe. Always thought that was signs of “ “too hot”.
