yeah, I'd have to disagree as well. Though different nutes are for different applications, you certainly can get nutes with the 13-14 necessary micro and macro nutes needed for herb. In non-inert substrates it's not even necessary since there are a chunk of them naturally in soils. Also almost all tap water will contain varying quantities of trace elements (copper, iron, mag, cal, etc). In the end, few grows actually need nutrients with every element required, and those using systems that need more complete nute packages should know it and pick the proper nutes (typically hydro lines).
Anyway, I grow in soil, and have had great luck with foxfarm nutes. Both the grow big and tiger bloom. On the slightly cheaper side I have also used fish emulsion and alaska brand bloom with success (the FF has near complete micro nutes though), though since I use filtered water I had to add mag/ca/fe with the alask brand stuff. The organics like fish emulsion are different though, they require microbial activity in the soil to break down into soluble forms. The FF is almost entirely soluble as is.
