I currently have seven heirloom varieties growing, but one of them is giving me a hard time. My marglobe has upturned leaves (not purple or purple veined) and these swollen stems at the joint. It doesn't seem to be growing as fast as the others, like my Black Prince and Cherokee Purple...all of my tomatoes are on the same feeding/water regime. The leaves, while being upturned, are otherwise in good shape (no holes, spots, rot)
Here is a photo to show what I'm trying to describe. I couldn't find anything online about it, maybe I wasn't using the right terms to search.
