How do you tell between cucumber mosaic virus versus downy mildew? My cucumber leaves are becoming discolored with blotchy/mottled looking leaves (lighter green and yellow in spots). Still producing lots of male and female flowers and there are about 7 cucumbers growing on my 3 plants right now. I pruned a bunch of the lower leaves, where the discoloration was the worst but it seems to be creeping up the whole plant. Newer leaves and still nice and green. Also, the actual cucumbers start out dark green and then get lighter in color, a very pale green halfway through growth. So, I’m not sure if I should just pick them early or wait until the grow more. When I left some to grow bigger, they seem to have a more bitter flavor. Smaller ones were sweeter. I tried to upload a photo but it’s saying that the size is too large and I don’t know how to make it smaller.
