green planet nutrients

Hello everyone! Been off the forum for about 9 years (wow..) but now that things are settled I have had the opportunity to start growing indoors. I don't have much experience indoors, only from watching others really...and mostly hydro at that. Vegged for 7 weeks. pH 5.8 - 6.0. Water with tap...

Growing in soil thinking of switching from advanced nutrients to medi 1. Is this a smart move or not ?
