Is this septoria?
I know just enough about growing tomatoes in containers to get the job done but certainly not nearly what I need to know. I was watering this morning and noticed spots on the lower leaves of all 3 of my container plants (one is about 15' from the others and the others are about a foot apart on the deck). One has just started to set fruit and the other 2 are in the blossom stage.
I looked at our Penn State co-op extension page and I THINK it's Septoria but can someone confirm? And if so, is Daconil what I need to go get?
