Yikes.
Okay... pale lower leaves in flower... not terrible.
Worry about those black spots first.
First off, go get a bottle of Serenade right away. It's an organic fungicide made of bacillus sp. bacteria that is perfectly safe to use in flower. Give your soil a good drench next time you water, using it as directed. That will help get the mold under control if that's what it is.
There's also the possibility of a viral infection, in which case your plant is cooked but youmight be able to limp it through flower anyway.
In the meanitme, Si, Ca, and K help your plant's immune system. A high K fert and some Silica Blast will be helpful.
Low humidity prevents mold. If you have LEAF mold, but rot is a DEFINITE. Get your %RH down to like 30% NOW.
Get your temps up in range too: D70-80 / N60-70.
urrr good luck... post back how it's going

Oh also if you have more than just that one plant, and you can isolate it from the healthy ones, DO IT!!!!
stinkyattic Reviewed by stinkyattic on . Have I got mold?? The picture is of my White widow leaf, 3 weeks into flowering. I think the lighter brown spots are mold and the darker littler spots are from a deficiency, I also think it might have a mild nitro def also. I cut a few leaves off the bottom-Middle that had these spots on them, but whatever it is is still spreading slowly. Could it be my humidity levels? It gets kind of cold at night and there is water in the air because of the moist dirt. Any suggestions appreciated, thanks. Rating: 5
