Ok so I took a few years off growing. Got back into it lastwinter and I keep having the same issue and can not figure it out. I start seeds and everything looks good for the first couple weeks they get about 6" then stop growing they get tight internodes, and the larger lower leaves start going yellow. At first I thought it was no N but I give it a good watering and still nothing. Plants are 6 weeks old 2 are about 10" and 6 are around 6". No noticeable growth in weeks.
