ok sorry its been a while. But first your still over watering. the amount may be right but you got to let soil dry out before you water again or 95% dry.
try 1 gal pots, not 6 in. and again the only thing you use on your plants from walmart is super thive. never MG or all the other bull shit and if that is your only option and you just feel you got to grow you better dilute majorly.
ill post some pics of my newest grow
