Leaves

I don't know what the problem is but, besides the problems, do they seem to be on track otherwise? Definitely not going to win any beauty contest, but that doesn't mean much if you are getting good tomatoes. Last year I had a bunch of warts on a plant, but it seemed to grow normally. The leaves are an unusual green color, but that's just me.

the bumps on the stem =root initials. Often on stressed plants and/or high humidity.

Any chance you used a weed killer on the lawn/grass, or a weed-n-feed?

I did use a weed-n-feed in the yard near the garden but the grass I have been using for mulching comes from the front yard that wasn't treated at all. Could the weed-n-feed have leeched into the soil and caused this problem??

the leaf picture is too much nitrogen

I've read that low potassium can cause woody stems.
