I called Western Labs to see about sending a tissue sample. I spoke with Harry and he asked me to send him a few pics.
He got back to me right away and said that it appears to be " bacterial leaf spot ". He said to apply copper fungicide right away.
The copper seemed to stop it pretty good. I had to apply another time after last weekends rain. It seemed to get some spreading again.
This bacteria spreads like wild fire under warm humid conditions. Rain makes it spread even faster from water splash. And I usually spray with a stihl fogger in the morning,when the dew is all over my plants, probably spreading the bacteria myself.
The absolute giveaway to know for sure if you have this , is the water soaked appearance to the back of the leaves.
The next pic will show the back of a leaf with the water soaked look.
