Looks like one of my plants has mold on it anyway to save it? I only see two big branches with it but they are the biggest buds 
There are products available that are not chemically made. If your plants are young enough they will absorb these natural plant oils as a foliar feed therefor not there when buds are smoked. This is only guess from a guy with only little experience. But may point you in the right direction. ILGM has a line of products for different situations. I have used these products and found happy relief when I noticed that they worked the first time.
I watched a video for something organic named Milde Cure I bought some on Amazon I will let y’all know how it works. Happy growing
