SeedlingsOnce a tomato seed has sprouted it doesn't need a lot of water. You are probably watering too much and this causes root rot. also they don't need a lot of fertalizer until about two weeks before you want to pick fruit. When seedlings get too tall they are reaching for light. Your light source should be 2 inches above tops of seedlings. Moving as they grow. Also a bit of a breeze on seedlings helps make their stems grow stronger. a small fan is useful. Good Luck, it's always trial and error.
