Is it a Fungus problem ?

I have a white Widow strain that I believe might have a fungus problem due to humidity temperatures were too high. They are back outdoors but don't know what to do ! The leaves are like yellowish/Brown and wilting down.. What do I do !!???!

looks like heat burn

Ur Ph has been out possibly. Cut off that damaged growth. I've had a similar problem recently. Was ur PH too low or were u buffering ur water too much. Looks like a P or K def.

Well I use distilled water with veg nutrients. My other plant is ok but another white widow strain is showing the same damage. I had them in my loft for a few days which can get extremely hot & humid ! I also had a lack of air circulation in that room.. I was wondering if it's like fungus or something. They were crinkling and it seems to spread thats why I thought she was diseased. I did cut off alot already. Heat burn ? How would you figure that out ? They are outdoors..

What can I do for a K deficiency ? P is K is it not ...? K is the letter in the periodic table for potassium.
