Tomato disease: Septoria leaf spot?
Anyone else in NE having this problem? Tomato leaves yellowing with dark spots in the centers of the yellow areas. I googled "tomato diseases" and think this is Septoria leaf spot. Only on all 6 of the Early Girl plants, not on other varieties. Sorry I can't post pictures; but google "tomato diseases" and click on "Septoria leaf spot" and you'll see photos.
If your plants have this, where did you buy them?
