Powdery Mildew in flower

I have powdery mildew in flower. I don't really know what to do, I have plants at all different stages of flowering, so I can't harvest early..maybe one..or two plants. I have been fending it off pretty well with plucking off the fan leaves that show it as my humidity is around 40% with lights on. I think that the humidity is going over 50 with the lights off and causing it to come back. I know people say to use milk and water and spray em down...and also use like peroxide and water...and maybe feed with some neem oil? i just don't want to mess up any of the late flowering plants by spraying them with the milk.

I am a big fan of the milk and water mix I would think twice about neem spray and drench in flower especially on buds you can burn all the hairs off and poison yourself or others. Dehumidifies work well and my grow does the same thing with humidity when the lights go out. Also I wouldn't pull the fan leaves unless they are totally covered you need leaves to grow buds. You could always put some neem on a towel or whatever and apply to the leaves. Hope this helps.

yes it does. thanks! what ratio to you use with your milk/water? 1/9?

A couple of tablespoons in a quart spray bottle should do the trick.
