Leaves canoeing help

So I have a few plants where the leaves are curling upwards at the top of the plant, I think I have gotten it narrowed down to over watering or heat stress. They are gelato 33, the the temps have been 70-78 roughly wit the occasional low 80 every now and then, been watering about every 3 or 4 days, can anyone help diagnose this

I’m doing gelato right now too and I’ve had canoes pretty much all the way through. I’ve decided that it has too do with my soil being a little too hot and maybe heat stress, but I’m pretty sure it’s not heat because my tent reaches 81 F at the most. I’ve noticed burned tips appearing with quarter strength nutes so I’ve been keeping the feeding to a minimum and it seems they’re loving it. Just cover your bases with preventative pest control and be really careful with the amount you feed and I think you’re golden. Good luck mang.

My experience has been light stress
