Plant leaves sticking straight up !

Hello, The Leaves of my plants are sticking straight up in the air, Does anyone know what the cause could be ?

Happy plants with enough nutes and light? Pictures help

heat stress? temps?

In my experience either heat stress alone or heat stress combined with intense light, nearly always HID.

My plants are always happy when teir leaves are sticking up.

need pics please ..

might be looking for light (if the hole leaf is sticking up)

happy plants can do it .. but not much and the most is the leaf`s point up like a canoe if that make any sense ..

heat stress is the leaf edges that point upwards ..

so many things to choose from .. pics please ..

i think the term is "craning"
OP: are your leaves curled at the edges too?

It looks like that after the night cycle, then during the day it will gradually come down. But I am still having problems with droppy leaves and low leaves dying. Refer to https://www.rollitup.org/marijuana-plant-problems/568277-plants-dying-after-i-switched.html

Thanks !

Way too early to switch to 12/12 lmaoooo

sounds like a humidity issue.

and how is it too early to switch to 12/12?
