These peas were started indoors about 4 weeks ago. They were aclimated before transplanting. I planted them in the ground last week and they have done wonderful. However when I came home from work last night I noticed there is some silvery streaking as well as some yellowing on some of the top leaves. (see picture) non of it is raised or pitted. It doesnt seem to be mildew but im not an expert. If anyone can help it would be greatly appreciated.
