look at my profile pic. I didnt grow it hee but thats a pic of a 10 day old plant in regular miracle grow potting soil under 2 10 dollar walmart gro lites.. Do not use the organic mix , although it seems like common sense, its not as good, or maybe too good, heee. Just use the regular with the 1 to 3 month slow feed nutes. The only problems may be with some strains u get a tad fertilizer burn on bottom leaves and a lil curling up but when it kiks in u will notice a spurt of growth. Dont add any extra ferts until u flower. And if u do transplant into more miracle grow then wait 1 more month to add a mild fert maybe fish emulsion and potash. That is saying u flower at around 12 inches. At least thats what Ive heard. heee.
