Extreme heat!!! help pls

So i went away for 3 days and when i came back, the temperature was at 101 degrees (F) and there was little white freckle, or very tiny sprinkle shaped white things, covering the topsoil of the plants. (when looked at under a microscope [60x zoom], they look like little white globs of stuff with lots of fuzzy white hairs)

aim in the last week or so of flowering and was wondering if the high temperatures and the possibility of mold could ruin my crop....

the heat will give you problems for sure 101 is WAY to high, and the mold in the soil not sure if that will give you problems but I dont think it is good might throw you PH off and fuck things up

true. im trying my best to keep my temp down now but it seems much harder with the added lights. do you think that stint at 100 will hurt my yield?

yeah it will for sure hurt your yield, just do your best to get the temps under control and hope for the best
