Morning growsomebud, on seedlings like yours, I only feed them about a half a cup to 1 cup of water a day, seedlings don't like alot of water,
Overwatering them can slow them down bigly, I start my autos in big pots I don't transplant much anymore. I don't even water my soil before putting in the seed.
I just pour half a cup in a circle close to the stalk, maybe a little slower than transplanting, maybe, But I'm old and lazy now. And I never water to runoff.
I think your gonna do fine, just be easy on the water, an keep your led ,at the right height.
Peace.
Ps, everyone grows differently !!
