On my 2nd grow here i did ffof vs super soil i made vs miracle gro, the results are crazy!.. You should pit off miracle gro moisture control from walmart against growdot, won't cost much and it is fun to see walmart soil outgrow stuff
Water only the miracle gro until like week 5 or 6 then u can start LIGHTLY top dressing, like grow dots miracle gro has timed released nutes in the soil. The next time i use it i will water only until it shows signs of bottom leaf yellowing.
Edit, all my peppers outside are in miracle gro and me and the birds love the fruit they give us LOL
