miracle grow soil is fine.
Maybe add some perlite to keep things a bit looser, help with drainage.
Just know that miracle grow already has nutrients in there, so you dont need to add ferts at first.
Once your plants have been in it like a month or so, you can start light feeding.
But as long as your babies are nice and green, you probably dont need to add many nutes.yes, I've added 1/3 perlite...I've been in MG soil for about 6 weeks now...still green, with LST, have over 20 tops at this point, and some yellowing of the lower fan leaves...some new growth is a little disfigured, when admin nuts, what dose if FF nuts, should i begin with? I've bought the 6 pack from amazon.
