Congratulations on your good start. It often takes me more than a week to get seeds to sprout. You're at least doing something right.
One thing to watch for is damping off. That's where the soil is too wet and the stem dies at the soil surface. Once they sprout, you want the soil to be damp but not wet. I don't know how to describe how to tell the difference, but damping off gets a lot of us. Let them dry out a bit without drying out. And maybe try watering from the bottom and make sure they can drain. Slightly damp is what you are looking for, not wet.
Next for me is to provide lots of light. The recommendation I've seen is to have the light 2" from the plants so you need a way to adjust it as they grow. It also helps to have light hitting the plants from the side, either with extra lights or using reflectors. If you don't get enough light, they will grow spindly. Yours aren't too bad yet, but they appear headed that way. If they have to reach for light, they can get pretty bad.
