strange leaf issue, pics

i have two healthy plants here, but about 2 or 3 fan leaves right under the lights (closest to it) are doing this. i would assume it was light burn, but i thought light burn looked more like nute burn. again, its only on a couple large fan leaves that are closest to the light.
temps- 75-79 degrees F
-600 watt hps lighting
-coco/perlite
-tap water
-ph=5.7-6.2
-ec=1.3
-16 days into flower.
-runoff ec and runoff ph are both in check

It’s the leaves natural response to high temps/high light levels.

Basically the humidity at the leaf surface is lower than the humidity of the leaf surface and thus is causing leaf roll up.

Move your lights up.

for sure, thanks. its literally only happened to about 3 leaves. I moved my light up yesterday as far as it can go. the plants are done with their stretch, so I think I am in the clear as long as that was the only issue

idk why that first pic is not showing up,..at least for me its not. o well
