powdery mildew outdoors

i caught a couple spots of it on a few of my plants but im a little stumped on how this could happen as i heard people say you only get this when there is no circulation in your grow room but i grow outside so idk.

i need some organic ways to get rid of this stuff because my plants just started flowering about a week ago. the humidity around here is around 60% right now.

plus im in the process of flushing my plants due to a ph problem could the pm be a cause of overwatering?

I haven't ever had powdery mildew on my girls but get it all the time on my roses. I use 2 teaspoons of baking soda in a quart spray bottle along with a couple of drops of liquid soap. the soap helps it stick to the plant and the baking soda upsets the ph of the powdery mild. I hope this helps you out it always works on my roses....
