Not sure what causes this

Hey everyone. This is my first post here. Been growing for 3 years now. Occasionally I get leaves like this in flower. This plant in particular has a ton of it. It's been in flower for just just few days. I am running a 480watt full spectrum LED, with UV. Landlord controls the heat here and its hard to get it down, so my temps fluctuate in that tent from 80-86 when the lights on. Bc the heat is rocking here, it's also reducing my humidity. It's between 16 and 36. Not an ideal situation at all, and honestly very frustrating. Can anyone tell me what causes this leaf folding? I am using an amended CoM Stonington blend for soil, 5gal rain science bags. I dont really like them because they dry out really fast in my environment. Any input would be helpful! Thanks everyone!

sucks about the heat situation in your place. My guess based off what you've said and the pictures is its way to hot and dry . The leaves can't breath so they curl up like that. It could also just be genetics but I'm still thinking heat and humidity

You're VPD is way off.
Your plant is sucking up too much nutrients because of it, and its causing the start of nitrogen toxicity.
Gotta buy a humidifier as a minimum if you can't get the temps down.
I'd also reccomened to ge the temps down lol

Yep . Start of toxicity my friend

Thanks for your replies everyone. The breeder had informed me that these leaf curls were common in the progeny. Out of fear that I was going to head into nitrogen toxicity, I did not feed it for 1 month. It's day 50 now, never had any problems with the plant other than not feeding when I should have. Its a little more faded than I'd like it to be at this time (juuuust a little) but the buds are swelling just fine and the tent looks good otherwise.

Think you should start feeding again

Yea I started feeding at day 30 when I realized there was no toxicity, but it was a little late. It's day 50 now and I don't normally feed this late, but I did again today anyway, real light.
