Hey I said my fav..here's a bit more detail
Per gallon of water feeding every watering....just under half tsp miracle grow bloom booster, pinch or 1/8tsp or just under Epson salt and a bit of molasses 1/4tsp (every other watering)
The molasses is great cheating metals that might not be absorbed to easily in my alkaline soil(talked about further down) it also gives me some extra potassium, some of my plants are k hungry and I mainly give them the molasses every water(drop the Epson on those, extra molasses takes care of it)
I have a myriad of grows going on all different mixes and mediums .. I use that fertilizer mix for all but the true organic..
The soil is just as important imo
I get great results using mg African violet soil mixed equal parts with mg perlite..the organic miracle grow does not have time released nute balls if that's a concern for you and is a nice substitute.....I sort of combine organic gardening with my miracle grow a lot and get great results.. Chemical nutes aren't necessarily bad, especially since I'm not outdoors anymore with runoff going everywhere. I always reuse my soil and the root ball from the last crop is always left, the root hairs are really wonderful and fantastic for your rhizosphere secreting all kinds of yummies up to 2 years(so they say, I feel more like 6months to a year) they also loosen it up a bit like super coir. I add everything from the previous harvest to keep the soil texture how I like, organic matter is important with the predominantly "soiless" mix. I add the stems and all fan leaves from harvest.. I like to add a little bone meal, it raises the ph slightly and gives a bit of calcium. I have pretty clean tap water.. I also add black ash(biochar) not fully burnt from my ashtray as well..I like to feed every watering and allowed to with the higher ph or buffering capacity.. together this increases water/nute retention while being very airy with great drainage.
I believe there are many aspects of organics that improve plant growth and desirable traits, such as auxins hormones etc like blood meal, there's a lot in there besides nute ratios..but nute ratios and the type of nute imo is most important.
It may not be the best but its cheap..all yearly costs, equal 37¢ per gram and I get great results..I mainly grow landrace sativas
