Always start with miracle grow soil but.......

So it's just easier for me to go buy some top soil and mix it with perlite and miracle grow soil. I usually veg for a month or a little longer then flower. My question is when I throw them into flowering I usually start adding fox farm ferts big bloom, tiger bloom or at least the powder mixes, beastie blooms, and cha ching. Is it such a bad thing to add organic ferts to miracle grow soil after the ferts in the miracle grow soil are pretty much totally gone? Should I just use the powder bloom builders at stand alone strength? I'm looking for a little more bang out of my fertilizers but it needs to be able to be added to my 50/50 top soil miracle grow soil combo around flowering time. Any advice?

it depend how your MG soil, as for myself i have expreince with MG soil before...before i plant in the soil, i just water soil and lets sit out for few days then again water at least for another week so you can plant in there...and after one month , i will flush the soil and its important to pay attention to your plant if they re still getting nutes from soil as long as you see the leaves become light green its time to feed him with those foxfarm ferts, if it s still greener after two months, try flush it again...otherwise , dont feed that plant or will get overfertilization. MG have very high of chemical in the soil already...I suggest you to find a organic soil it will be easy for you to feed foxfarm ferts early

BTW i had two plants got burned from this MG soil, i learned my lesson. i will always still buy MG soil if i dont have any fertilizer liqiuds

I am very lazy. I guess I should just buy top soil and mix that with a few things to loosen it up drainage wise. I guess my question was more along the lines of should I use organic after the plant has been living on chemical ferts for the first month before they were used up (miracle grow). I'm also really watching my ph's because I think that's building up more than expected. My water is like 7.8 by itself so needless to say I own ph down.
