I've got 4 spacequeen seedlings that are now 1 week old, but I'm getting some browning on the leaves and a little black.

The setup goes: 225w cfl in a rubbermaid tub
Temp: 80f with a fan blowing on them
Soil is just basic stuff for now, but have organic for the transplant, I didn't want to burn them as seedlings.

Any help would be appriciated, as I want to see these grow to their potential. If you need more info or pics, just let me know and I'll get it up here for you. Thanks in advance.

edit: for some reason it woun't let me upload the pics, I'll have to try a little later, sorry.
