Cute seedlings. perhaps its the Camera light but they look a tad yellow. If this is the case, is your soil pre-nuted?

If not, forgive a stoner in the morning

Now your cabinet set up... That is some dope shit man. Wanna come build me one of those? :P

Also your partner in crime is wrong unless they're 2 weeks old. some strains can handle ferts earlier but 2 weeks is just the safe mark for nutes. (also start with 1/4 the reccomended dose, then 1/2 then the full)
