That looks like a natural Alligator Tail. It doesn't look like heat. The leaves are bright and healthy.
Nice plants.

because of the size of the pots im watering every 2-3 days and the RH well... my meter reader broke and I havent replaced it. But before it did I would say anywhere between 35-45

it's either #1 or #2, may be #3 but if you haven't sprayed i would do it NOW just to be sure.
also post what strain it is because if it's a Sour strain like a sour diesel then that could just be the genetics.
1) humidity is too low, or temps are too high.
2) light burn, or introduction to a powerful light without slow acclimation.
2.a.) download a lux meter app for your phone and post how many you are getting at the location of the curled leaves and post that number here.
3) have you already sprayed for pests? I recommend Spinosad by Montery because it smells better than neem oil and it's a lot safer than Pyrethrins if you get it on your hands. Also and you don't have to take the plants outside to spray cuz it doesn't stink and won't cause drooping like Neem or pyrethrins. Plus Pyrethhrins are deadly to our good friend the bees - and we can't live without Bees.
4) root bound, your pot isn't large enough. how long did you Veg for?

I found this too, since it could be a disease you might want to read up on it.

as you and Drwho imply canoing leaves(with weed) is a temperature Rh thing
see it, as the plant trying to shed that excess heat and stay awake,
once temps excedd their limit plants fall dormant
thats bad and screws with harvest date
see to your temp and relative humidity
good luck

The fungus T. deformans causes deformed young leaves on peach and nectarine trees
