When my leaves curl from heat, they roll up or fold up like a taco shell shape. If you’re asking about the tips of the leaves- I think it is just very mild nute burn (hard to tell exactly due to very little brown). I would wait and see if it progresses. I’m no expert though. I have grown mine in much hotter temps and when the temps were lowered the leaves went back to normal. Post new pics in a few days or sooner if you see any progression of the problem.

i was meaning the rolling up or fold up like a taco shell thing. heat stress ??

And I agree, that’s what mine did when I got a stronger light.

i have about 4 weeks left so im hoping it don't worsen
