Quick + easy nute recommendations please.

I'm sure this is a really easy question but it's still a needed one: What types of nutrients should I be giving my plant at this stage?

Right now it's about a week or so from seed (Germinated with paper towels, no chemicals) but I waited a while to plant it (Kept it all nice and moist, seemed fine.); so it's still a seedling. I planted it into plain ol' topsoil since I figured it could get nute burn if I threw it into miracle grow or something like that from the get go.

Would bonemeal (4-14-0) be a good nute to use at this stage? That' what I already added (Sadly before asking), but I only added like a teaspoon at that and it's a decent sized pot. (You could palm the pot pretty easy, if you get what I'm saying.)

BTW- Lighting is as follows: 1 25ish watt cool CFL + 2 42ish watt warm CFL's, all super reflected since it's in a egg carton lined with white cardboard paper and has a bigass mirror on top of it. Ventilation + humidtity is also good with a fan + humidifier taking care of that shit.

Water PH is a bit less then 7, learning more to alkaline, but I think that's a good thing, right?

Thanks for the help.

The seedling does not need any nutes right now, if the ph was less then 7 it would be acidic not alkaline.

with seedlings I use a product called Propogator from Future Harvest Develepment. There are other products like it but this is one i got incredable root growth from with in a week on adding. Great start to my plants. Seedlings due need something unless your soil has enough in it. PH should be about 6-6.5 the most.
