Man brother that sucks about the mold! I feel for you. I am only on the start of my 2nd grow so I have no advice for uses of the budzzz that have it. You have some very nice colas going though! Looks stellar. I have to back track and see what strain you are growing. Some strains are more mold resistant. IDK if that is bud rot??? Or the beginning of it??? I have a lot to learn myself. I would definitely open your canopy up more next round and try to pull all the dead leaves and do some defoliation as you get late in flower. It will definitely help IMO. Some people don't defoliate at all. I believe in it. I think
@Aquaman told me to keep my lights out temps same as day to help prevent P.M. and bud rot. Hopefully you will not lose much. I think cooler temps at night cause the purple in flower from what I read. Maybe in veg its stress and or nutrition issues? Other than the fungal issues you look dialed in pretty well.
at least in this rookies eyes.
