Brown/yellowing of tomato plant leaves - help?

My tomato plants are suffering from yellowing/browning leaves. It started about three weeks ago at the bottom of each plant and it's spreading upward. I worried it was early blight, but at that time, there were no distinct brown circles on the leaves, just splotches of brown and yellow. Now there are some distinct circles on some leaves of some plants, but others do not have it.

Can anyone help me identify the problem and let me know how to treat it? Thanks so much in advance!

here are photos of one plant:

And here is the plant next to it:
