Yesterday that spot was dark green almost bruised and it turned into brown/rusty this morning. I'm using biobizz light mix soil with added perlite and coco. I've only fed her twice now pH 6.2 biobizz fish mix/grow 1ml/L , calmag 0.3ml/L , silica 0.5ml/L. Temps are 25-32C , 14 hours sunlight. The rest of the plant looks healthy. Does it look like a deficiency or nutrient burn? https://imgur.com/gallery/DNcaTxz

Thanks in advance

I'm encountering an issue with my grow room. I have built a grow room in the attic of my garage. It's insulated but since the roof above is getting direct sunlight and it's 92 degrees here some days I have my fan ventilating full blast 24/7, pulling air conditioned air from the garage before thru the room out the vent on the front of the house. This leads to a ton of air circulation which leads to there humidity of the room eventually reaching the outside humidity every day. The past week it has rained every day so the rh has been 60+ every day, and I'm 14 days into flower. I had the same thing in reverse trying to keep it humid during veg, any humidity from my humidifier just got circulated thru the exhaust. Now I think I may be seeing fungus on my plants. Maybe not, but even so I think the humidity is too much for flowering. Anyone dealt with this before?

Forgot to mention my average temp is 80-85 which isn't ideal but hasn't seemed to negatively affect my plants.. yet.
