i'm a rookie and admittedly have not read the thread.
that said... sure stretched on ya' didn't it? if it were mine, i would re-pot it, burying it all the way up to those little starter leaves. then, whatever light you are using, i would get it down closer. water with a light, say 25% strength feeding of your preferred base nutes, wait 1 day (wanna let it dry out a bit), plain water, wait 1 day, feed, like that...
That's just what i would do.
Good luck bro!

*edit* on second thought, being that young i would not give it any nutes yet, the new soil will contain plenty, but still skip a day between waterings.
