Leaves Curling Up on my white widow baby

My plant has been in hydro since birth. They are feminized white widows born into rockwool and put into hydros. This one has started to curl upwards slightly on the sides. I cant find anything similar to my problem on the FAQ's.
Anyone have any ideas

i find that when my temps get too high the leaves start praying like that. what are your temps like?

I am not too sure, what is a good temp to have?

A humidity and temperature gauge are essential in any growroom. Daytime conditions should be 70-80 degrees without co2, 80-90 degrees with co2 until the last two weeks when daytime temps should be kept between 70-80 and co2 can be reduced to adjust for the lower metabolism. Night temperatures should be kept above 60 degrees to prevent stress. It is preferrable during flowering to have a night temperature drop of 10-20 degrees to stimulate flowering hormones and reduce stem elongation.

i agree with you that its heat stress but ftr thats not praying leaves, its canoeing leaf or cupping. when they are praying the stems are sticking straight into the sky and that is not from any stress it means you have a healthy and happy, thriving plant.

yep i think heat stress too
but yeah there not praying
dont know but i wanna know for sure what it is

Too much water, poor drainage.

OR

magnesium deficiency, fix with Epsom salts 1/4 teaspoon per gallon of water.

Peace
