What kind of tomato problem is this?
This plant was doing just fine, then all of a sudden it started wilting and it has yellow leaves on bottom and brown leaves on top. There are a few tomatoes on the plant that seem to be OK. I've looked at pictures and can't quite determine what this is... maybe early blight?
All other plants look fantastic and are now towering over this poor thing. Should I chop this down? Is this problem likely to transfer to other plants? Thanks in advance!
