While I was weeding the plot this morning, I noticed sky blue marks on
broad bean leaves. On further inspection, I found the same on French
beans and peas. Some just spots, others about 5p size. It wipes off
with a wet finger. Any ideas as to what this could be?

Has someone been using Bordeaux mixture near your plants?
