Please help identify tomato leaf spots?

Hi, I'm new to gardening and new to the forum. I bought a couple of nice looking tomato plants from an old guy at our local farmer's market two weeks ago. One was a Cherokee Purple, and one was a Sweet 100 cherry tomato. The Cherokee purple looks great.

Problem is, I started noticing about a week ago some darker green looking spots on the mature leaves of the Sweet 100. My first thought was that it was blight and I should pitch it immediately... but it doesn't LOOK like the pictures of blight that I see online. The leaves have slowly gotten more spots, but the spots died. There's no discoloration other than the dead spots.

Note on the image: there's no white on the leaves, that's just reflection from the flash that you see.

If anyone could identify this, tell me if I should rip out the plant or if not, how to treat it, I would be greatly appreciative. I have no idea what I'm doing, and no one to teach me how to garden. :/

This doesn't look like a disease and, you're right, it's definitely not blight.

Looks like insect damage to me.

I agree with Lionheart... looks like snail damage to me... they have a rasping mouthpart that can do this. The sweet 100 is a tough plant to begin with. And one of my favorite cherries.

Hi guys, thanks for the "not-blight" info, I will refrain from ripping it out and burning it.

One note, it's possible that it had snails before I bought it, but I didn't notice spots when I bought it, then it sat in my house for a week, with me checking on it every day (no snails or bugs) and i started to notice those spots developing. They started out darker green, and then eventually became the sunken, dried, brown spots that you see in the photos. Does that help any?

Nothing ate the tissue. Instead the cells collapsed due to a cultrual/environemental glitch.

As a starter list consider these: Perhaps not hardened off enough; windy; to warm; inadequate water; root damage.
