Leaf

Some plants just do this for no reason.

Leaves are curling up that way due to heat. You can see this with the way it happens less so at the bottom. The tips are damaged either from nutrient burn, or because of the extra water transportation due to the high heat (basically it drinks quicker to combat the hear and can cause nute burn by eating faster than usual basically) If you can dim your lights do that otherwise I'd suggest you raise your lights.

Check your nutrient schedule 🍀

Bruh what!? Leaf?

They look great. Really green. Probably maybe too much nitrogen for the flowering stage. I would cut the nitro and focus on blooming nutrients from now on Cheers 🤙
