Well, most of my tomatoes have what I believe to be some form of blight, I just started noticing this today. I looks like the dreaded rings are on some of the lower leaves. I did end up getting blight on my tomatoes last year as well, but that was later in the season. I know there really isn't much that can be done once tomato plants get this, but maybe I haven't heard of something. We got record rainfall in June (mainly from thunderstorms dumping 2-3 inches on us at a time). Let me know if I can control this some way? (Oh and I did mulch with grass, which didn't seem to stop soil splash up.) I should have learned from last year, and cut all the low laying branches, so there was no dirt splash up.
