 No, it's on the cucumber. On the cucumber. On the leaf itself. Well, I have the same problem. We're getting a little powdery mildew and a little leaf spot from the humidity. I would pick them off. And if you want to spray them, spray them with a fungicide. That will help eliminate them. There's a couple of different options. One's called Garden Foss, which is organic. And the second one is Fung Oil or Daconil, which is a contact chemical.
