In my last grow I had some problems with powdery mildew, but I didn't realize how serious it was until everything was totally screwed up.
Since then I've read, seen photos, and learned what to look for. In searching for a product to kill PM, I found something on the internet saying that mixing milk with water does a good job, as milk is a natural fungicide, and even has some small nutrition value.
So I've been making a 25% milk 75% water combination, and I keep a close eye out for any spots of PM, and I spray them down HARD when I see them. I'll even dip my fingers in a glass of milk/water and rub down leaves that have a spot of PM on them to help work it in and wipe out the PM.
It also seems to kill spider mites pretty well, as I saw a few on a couple plants, sprayed them, and they haven't come back in over a week now.
Anyone else ever use milk/water for this?
Since milk is a natural thing, I wonder if it is ok for it to be sprayed on leaves and buds during flowering. Any idea?
