I’ve ran 30c at 60% rh for a couple weeks straight. Then dropped it back to 25c and 50% rh never noticed a difference in growth at all.

I beg to differ on that. It comes down to infrared light. The LED's don't have much IR therefore the leaf surface temperature doesn't reach the temperature required for optimal metabolic rates unless you have the air warmer than you would want with HPS.

Ugh bro science I don’t think so it’s just to open of the stomata of the plant letting it eat correctly and to transpire better I don’t think that’s bro science because I know for my plants if I’m under 80 they stop eating and it’s bad

u can grow under 27 C its just your not unlocking the potential of the plant youll still grow some fire bud as long and you don't give money to cammie
another reason people like running that high is dehumidifiers dont work as good when its cooler

Living in norther Canada I’ve never even thought about dehumidification LoL. I run humidifiers full blast 365 days a year here. I’m going to up my room temps right now and see how they react over the rest of the grow.

I run the inkbird temp and humidity controller so temps and humidity will stay wherever I set it. I just upped it to 32 Celsius and 55%rh

A broken clock is right twice a day!
I feel the same about coco: it can be great but it ended up being my worst enemy. I'm strictly inert mediums now.
Then it's a cal mag defecancy if it started once you stopped using cal mag you answered your own question in this post

More then just a Calmag issue here. Never seen serrated edges curl this bad with a calcium deficiency.
Yeah I'm also not sure why your leafs are curling cuz ik the calmag won't do that just the rustic looking spots with the calmag but it seems like your doing everything right so I'm baffled I've never had my plants curl like that only with a ph problem I've seen that on mine but your ph is good so idk but other then that but still beautiful girls
Good Luck and Good Growing

So I just re read that link you posted again, all 5 of those scenarios listed all have cupping leaves as symptoms. And it could be 4 out of the 5 listed (heat was exclude)
