Slow tomato seedling growth // Fast zucchini growth

Hello everyone,

This is the first year I am attempting to grow all of my plants from seeds. I started a little over two weeks ago and everything was going according to plan. The tomatoes sprouted in about 3-4 days and I immediately put them under a full spectrum grow light (8000 lumens). They get 18hrs of light per day and water every other day. The zucchini plants are growing really well, but my tomato plants have just stopped growing after about 1-2 inches. Its been over two weeks since germinations and they have purple stems and the undersides of their leaves are purple as well. I read somewhere that a Phosphorus deficiency could cause the purple color when the plants are in cooler environments. My plants are in my apartment and the temp never goes below 70F. Really hoping they sprout some true leaves so I can transplant and start adding fertilizer. Any advice for what I might be doing wrong? I have attached 3 images for your convince. Thanks!
