I've always assumed it was, but its hard to differentiate for me between SLS, Early Blight, and Anthracnose. I know i have Anthracnose from my fruit once they turn red, but the leaf disease starts long before that.

Definitely looks like it. As I just noted on your intro post, I get that on almost everything, in these years when the moisture is excessive. This year I tried a new one, for me, and it is the only one with no septoria - Mountaineer Pride. Resistant to that and LB, and I think fusarium and verticillium wilts, also.

Good to have a confirmation. I definitely have multiple diseases going on, but septoria is the dominant one, and is only beaten by the resistant varities (that plant pictured was a volunteer thats not resistant)
