Mold

[growingsomething]

I'm in the late flowering stage of most of my outdoor plants and I'm noticing some white spots forming on the leaves. I'm in NorCal where there is a lot of ash in the air so it's hard for me to tell what's what. Also the humidity is pretty (73%) it's usually around 50% and there is some brown growth in some of my nugs which I think is bud rot. Got any tips to combat humidity and possible mold?
Thanks
