Most noobs (not all) will buy the label and not botanical principles, plant nutrition. They're lazy, want to be taken care of which folks like Advance Shysters is more than willing to do.
If you can't raise some beautiful plants with rock solid colas (like my avatar) with nothing more than something like Walmart's or Jack's 20-20-20, FROM START TO FINISH, you shouldn't be growing. I raised that avatar plant using mainly organics like blood meal, bone meal, etc. but with tweaks of cheap off the shelf plant food and the 5" diameter cola was solid bud. I'm talking solid. Air could not get thru it. I had the genetics too, mainly indica.
This is my philosophy and advice to a fella who's well on his way to becoming a Master Gardener -->
