I took a leaf stem and peeled back the "skin" to see if they were internal or attached. It peeled back with the skin and inside was not infected or discolored. I think it is a mildew or fungus. The specks are semi transparent.

The Seranade and sulphur I used was not effective. I think I will try a potassium bicarbonate soloution. What do you think?
