Heat stress i think. Recovery?

Hi.
Got some pretty unhappy plants at the mo. They are 7 weeks flowering, White Widow.

Had a problem with spider mites, but under control now. Was also struggling with grow-room temps. I was hitting 35-36 oC (96oF) at times. Again, this should be sorted. I've insulated the room from the heat coming from the roof tiles above + i've added an intake fan (i was using passive intake) so temps max at 30oC (86-87oF) now.

Some of the leaves have clearly taken a battering. Will they recover? or just stay burnt up? I'm unsure if i'm doing anything else wrong as well. Is there anything else that looks bad? over-nute maybe?

thanks in advance

7 weeks into to flower so you have about 2-3 weeks left, buy a bigger fan and give her cool water instead of room temperature water if its heat stress.

chop tha badest of the bad looking leaves and lots of water and air flow.

Nah, the leaves won't recover, but not to be worried about. At 7 weeks in, considering the mites and the high temps, they look pretty good. All you can really do, at this point, is take care of 'em, and wait for harvest time.
