there's a shit ton of different ways to get the same results
yup There's a lot of growers that alternate between feedings, like: synth. feed - organic tea - synth feed - organic tea etc., plants look great.
Also, for example, everyone says to cook your soil for weeks or months, well i don't cook my soil, i mix a ton of amendments in it and at most it gets to sit for one week, sometimes i transplant the day of, plants always look bitchen' and healthy and happy
(i don't use blood meal, and very little bone meal though, so that's my excuse i guess lol, oh and i reuse my soil and reammend, so yeah, that's my other excuse)
