Hello,
I planted tomato seeds indoors on March 18th. I used a heat mat and the seeds germinated and are now seedlings growing under a plant light. However, some of the plant"s leaves are starting to yellow and some of them have dropped their two first leaves. Why are the leaves yellowing and what can I do to keep them going until I can transplant outdoors in mid-May?
Thank you!

Expert Response
I think the grow light needs to be evaluated for the needed light and soil for tomatoes. The soil may need nutrients.
Also, the plants may need more sunlight.
There has been questioning about the quality of the plant light kits from dollar stores.
