hi all i have 4 seedlings going right now that i plan on moving outdoors, i started them about 2 and a half weeks ago, moneys a little tight now so i cant get the fox farm trio pack for another couple of weeks how long will i be able to get by with the the nutes that came in the soil and if not should i use miracle grow nutes for the first feeding and then just flush and start fresh with the fox farm nutes
