Tomato plant issue
Baltimore County Maryland
The tomato in the left photo shows adventitious roots on the stem. These are adventitious roots or aerial roots which would grow into normal roots if placed in contact with the soil. The degree to which a gardener will see this is determined by cultivar, weather conditions, and culture. http://extension.umd.edu/hgic/adventitious-roots-vegetables
It looks like the tomato is still in the container. You should remove the container for better root growth.
The tomato in the middle and right photo looks healthy and we do not see a problem. Here is our profile on tomatoes http://extension.umd.edu/hgic/learn/tomatoes
