I have a Blueberry AK plant outdoors about 1/2 way into flower - I figure 4-5 weeks to go.
I noticed some very faint 1/4" spots on a couple of leaves. Almost looked like a light frost/frozen spot.
Looked under my scope and it looked like fine webbing. I'm guessing it may be the beginning of PW.
I only found 3 leaves with a spot or two and removed them.
I figure if I caught it soon enough it shouldn't take much to keep it at bay.
Is it safe to spray the whole plant down with baking soda or H2O2 while in flower?
I can see if I can get a sample picture tomorrow. My phone was dead when I was looking earlier so I didn't get any pics up close of the leaves.
As for a source I didn't see any obvious sources around it in the yard.. Maybe the morning glories nearby on a trellis. But I didn't see any mildew on their leaves.
Here’s the plant
