This is my first time growing tomato seedlings. They are 3 weeks old
and growing large. All was going well until today I noticed some of
the older leaves on the Brandywine plants are begining to discolor. It
almost looks like the green is rubbing off in a large blotch in the
center of the leaf. The color is paler that the rest of the leaves. I
haven't been able to find any photos of diseases that look similar.
