Heirloom Tomato Leaf Problem
All my tomatoes have recently become afflicted with some sort of leaf disease. I went with heirloom varieties this year, and it looks like I might lose them all. I've looked for similar photos, but have not found anything exactly like what I'm seeing on my plants. I could have a problem with septoria or bacterial spot, and don't know where to go from here. I'd really appreciate some advice. I'll try and post a photo link below. Thanks in advance.
