Welcome to NGA,
@Jpbunka !
Tomatoes are subject to a number of different diseases... mine always are infected with something -- for years I assumed it was "blight," but I now believe it is either fusarium or verticillium wilt -- but they mostly grow faster than the disease can keep up with and provide me with lots of tomatoes, so I just don't worry about it all that much. I would suggest spraying your plants with Daconil and fertilizing them with a balanced fertilizer.
