Yeah, superthrive is safe for seedlings. It's not food (no NPK), just growth hormones like thiamine.

Distilled water isn't necessary or even really advisable for anything but flushing. Your regular tap water has calcium and magnesium in it, which are necessary for plant grotwth and resistance to stress. If you want to use distilled water, you are going to want to do what hydro folks do and add some CalMagPlus.

If you're worried about the chorine in your tap water, let it sit in a wide bowl overnight to air-equilibrate. Most of the Cl will evaporate.
