When 12/12 from seed how long before fert?

When you 12/12 a plant from seed how soon do you need to fert? I've been giving her water and occasionaly some superthrive, But it appears yellowish in color and the stem is purple? This seed is from some pretty good chronic, So i'd prefer to keep tryin to bud her. Thanks RIU.

(The reason I put this in CFL is because thats what I'm running in my PC Grow Box)

...depends, if your growing in rich soil or not. What are you using for a medium?

i usually only use nutes when is visably needed.. the absolute earliest you should use nutes on seedlings is about 3 weeks, or when the first set of rounded leaves {corty's} die

The soil i'm using is that organic "supersoil potting soil"

So then her color shouldnt concern me too much right now?

dude how old is ur plant? also what kind of soil u got??? most decent soil will have enough of its own nutes to sustain the plant untill you can add nutes

It's organic "supersoil potting soil" and I believe it does have some plant food, Plants looking fine today though.
