Unknown problem

Temp and humidity are in check, ph in check, no bugs or anything visible, light is on point, does this curling look familiar to Anyone?

Looks like heat stress, or beginnings of light burn.... but with just an "in check'.. hard to say.

i second that, first thaughts were heat stress also. some plants prefer a cooler temprature

But he said check guys so..........lol jk. It certainly does look like heat stress. Is it mainly on the upper foliage??

temps are 82f and 60% rh, running around 600 ppfd with leds. The curls can be found on the lowers as well, plants next to it are fine
