I'm not convinced re the septoria, though it would help to have a picture of the plant as well. But those leaves look very healthy, just discolored.
Septoria is a disease and along with the spots, it creates yellowed unhealthy leaves, with brown edges and getting raggedy, like this:
But I hadn't said anything, because I don't know what the problem is. Perhaps some nutritional deficiency? (because the leaves aren't particularly looking diseased) But I looked around a bit and haven't seen anything that looked like that...
Here's a couple more pictures of septoria and early blight
Not enough nitrogen tends to result in yellowed, pale leaves
But I seem to be a lot better on what it isn't, than what it is!
