leaving got the door open on autos to contro heat, shouldn’t be an issue. That’s what I do.

You have a lot more years of experience than I. It looks like nitrogen burn on the tips. I’d pull off the bottom leaf that looks a little funky.
My autos usually don’t show problems until they start to flower.
MIGRO on YouTube has a good video about DLI (daily light integral). Autos don’t need as much as photos, also depends on how many hours of light you give each day. ie- 20/4 18/6 etc.
check out vapor pressure deficient chart. If humidity and temp are off, the plant can transpire too much or too little causing nutrient issues. Say it’s real hot in the tent, and humidity is low. The plant will lose and take up water faster. As it takes up water it is taking up nutrients at a higher rate than it needs. This is a very stripped down explanation. VPD will change between seedling, veg, and flower as well. Mine are about the same size as yours right now, I’m at 76(ish) degrees and about 70% humidity. Both vary some through the day.
I have a 4” Infinity exhaust fan that can be programmed to speed up or down to keep heat one humidity in a certain range.
Very helpful.
If I’m telling you stuff you already know, my apologies ✌️
good luck
