could this be root rot?
Hello everyone, I posted a picture of this in the vegetable forum of this mark on a few of my tomato stems and I have another picture of it. It seems mostly on my black krim tomatoes. The plants are showing no signs of distress and look green and are perked up and look healthy to me. The marks have been there for at least a week and a half. The roots look white and healthy. Also if it is is there anything I can do about it? I up potted some of them and buried the stems deep. What do you guy's think? Thanks.
