High temp problems

Hello, im new to the forum but not new to the scene. I tried a new system but had to wait a week for my thermomitor to turn up.

When it did my room was at around 35-38 degrees. Iv managed to sort the temps out now but i was just wondering if high temps are my only problem. Or can they cause several deformities and stunt growth. My ph is on point and my ec levels seem fine, so im hoping its purely the temps doing this but i cant manage to find any info online.

Anyway here are the pics, im hoping they will soon spring back to life after being punnished with the heat.

P.s they are clones and only got transplanted in there last week. They were perfectly fine before. Iv only fed them twice so cant see it being root rot either

i would just get them in more favorable conditions and just water for a while, good luck
