Planted Tomatoes Having Problems
I planted tomatoes around Valentine's Day and now they look a little yellowish. They are about 2 1/2-3 inches high in 3-inch pots. I've used seed starter potting and planting mix. Plus I have a heat lamp on them with temps between 70-80 degrees, and they are in the sunshine when available. I water them every two days, sometimes I water the bottom of the pots, or from the top. I haven't fertilized them yet, but I still don't like the yellow look.

They need nitrogen. Give them a weak solution of fertilizer to fix this.
