 o
Bacterial speck, septoria or something else?

A couple days ago, I noticed it looked like some of the leaves of my tomato plants were turning black in places. Upon further inspection, there are many black specks comprising the black areas. I sprayed with copper yesterday (as I have been, but the rain isn't helping that) and this morning, the black has spread and looks much worse. I also see some brownish, dry looking spots that I think are septoria, but a good portion of the leaves have the black specks on them and it's getting worse. So far, I haven't noticed anything on my other plants, save a couple leaves with just a few tiny specks that I suppose I should remove.

I think this is bacterial speck and maybe some septoria as well, but I'm worried it could be TSWV. My cooperative extension office can't help. The plant guy is on vacation until next week and VA Tech's lab is closed until August. I'm hoping someone here can give me some info.

The last picture is what I think is environmental damage on another plant, but I posted that to see if I could get confirmation of my suspicion.

Hi, can't exactly tell but .. on your last picture, that may be flea beetles. Little black flea-like ones that jump from leaf to leaf and suck juices out. They sometimes have alot of little circles together. From reading, I believe they won't kill off your plant. Seems to happen in the beginning of the year. Once plant growing strong, these are going away in mine.
