I tend to overheat my canopy a lot. Leaf curl is first sign my gals show and tip burn follows. Sometimes my room feels good but i check my canopy temp and its 90 . I vote leaf temperature.
I got this curling on a couple of new plants in the dome. Not exactly sure why. Temp and humidity was on the high side 78-81F and 70RH. But also ran close to the LED strips. Building a dome riser for two in the oven right now.
Disappeared on new growth after transplanting to the tent.
