Tomato Seedlings seem to be growing really slowly
New to this forum, but have been doing several types of gardenings for years. This is my first year starting tomatos from seed, but I may be doing something wrong.
Here is a picture of part of my lot that is about 3 weeks old, maybe older, I stupidly didn't write a seed date on these guys.
They seem really small compared to other peoples tomatoes, and I uprooted one to check and the root growth seems minimal. Any input would be great.
