Everything was fine, but whats now? :(

There is pictures of my plants. I have 5 plants, on top all look good, but 2 plants on bottom looks very bad. Flowers on bottom is getting dark brown. I hope my plants will not die ;(

I use 1L water after 3 days and nutrients with NPK 3-6-6 ...



I'm scared only about humidity it is around 70-75% which is high :/

Hope to get some good answer...

I'm in day 19 of flowering!!!

I read some information and it looks like MOLD ... And it cause from humidity... How can I decrease my humidity?

dehumidifier and ventilation.

My pots was very very wet, I think I was overwater them... Just bought dehumidifier and try to move more fresh air... But I don't believe my Chines humidity meter It show 73%, when I put dehumidifier, after some time it decrease to 65%, then I move around my grow room and again 71%... Hope it will help me some how... I cut all leaves with mold...

No ideas from any body else? Is it mold?

I cut all leaves with that sh*t on it. Would I need isolate sick plants now or what? No answers :/

Need help people!
