Alright, so I first got the powdery mildew problem about 2 weeks ago. It was originally very slight. It looked like a little dust on the leaves. It wasn't as bad as ANY of the pictures I've seen on here of it
we followed forums and ended up spraying it with vinegar water every 3 days. That worked, but the mold would slightly come back every 3 days.. Not hardly as bad as it was before
then we flushed and used serenade 2 weeks before harvest. The 6th day after using serenade I see a very, very slight powdery mildew on the leaves. It looks a little white under the hps light. Using a 100x microscope, I can only see 6-10 very sparse spores on the leaves I cut off because they were the worse.
I only have about 8 days until I harvest. I'm debating about what I should do. My gf things we should spray alkaline water on it. I'm thinking we should a) do nothing or b) spray more serenade on it and then make hash out of the plants, then running the hash through the screens again with pure water thus washing it.
I have 4 grand daddy purples. Here are pics:
Before we had any mold:
After we sprayed with serenade (note the crystals are because of the 600watt hps + 100 watt mecury vapor uvb lamp. There is no visable mold in these pictures)
