A few of the leaves on my raspberry have sort of went a gray color in large splotches, almost covering the leaf it was affecting. I cut those off, but since have noticed discoloration on a stem and holes in the leaves. I don't see any insects on the leaves, but there are thrips in the fruit. There is a branch that is crossing near the stem where it is black, and thought perhaps this could be the problem (rubbing), but included it along with the pictures of the leaves in case they are all related.
