Yeah, that is what that first photo looked like to me too. Was my first thought.

Though the way she described last year.... That sounds more like a blight...but not really because usually blights are fairly specific (cucurbits or kohls or nightshade).

Thanks for the tip. I hadn't heard of that before.
You too, @em3

But it is probably a result of leaf spot disease that has survived winter. That would explain why everything was infected last year... Unfortunately, there's not a whole lot you can do about it if you want to stay away from chemicals.
For now, I've cover all leafs with a thin layer of lava rock meal, which keeps the leaves dry and prevents fungus from spreading. Fingers crossed!
