Your temperature is fine, but you do have symptoms of over feeding, like the burnt tips and curled leaves. At this point you should stop all feeding and flush the media and let the plant finish with what's left on its reserves

Don't worries , no sign of reveg here , especialy from an auto strain but the brown spot on the edge of your leaves could be due to a little overwtering . Your temp is not good , way too high but it will mostly slow your grow than burn your leaves ! Maybe the fan is too close ! But your problems are minors , your plant is prettu healthy bro 😘

The leaf color change could be a variety of things... Nutrient deficiency, PH issues, etc. But I don't think its heat related specifically. In fact in your case I think its just a sign you are getting close to harvest. It is not uncommon for leaves to change color and fall when getting close to harvest. Just like the trees outdoors that change colors and drop leaves in the Autumn. Here I think its a good sign. I'd recommend you keep on doing what you're doing. She looks great so far! 👍
