Any lineup that has a dozen products is scamming you... The only thing that shouldn't be combined is Ca / Si with P / S in high concentrations - it is fine at normal fertilization concentrations, of course. Anythign with microbes should be it's own thing.. and, anything like humic or fulvic acid i'm not sure, but probably won't find those mixed in. soil is more complicated that soilless/hydro nutrients. With soilless/hydro, you need 2-3 parts to cover everything.
More is just an extenda-penis and a clever way to convince peopel to spend 10x more money than necessary on products with a huge profit margine and some sugary-cereal-like cartoon logo on the front.
Don't overpay for ubiquitous commodities that are ingredients for fertilizers...
dry nutes have a long shelf life. I buy 2 25lbs bags every 3-4 years. I spend about 30-35 usd / year on fertilizer for 2 cycles of about 40sq ft per year.
These products have been on the market in various forms for a long, long time.. there are no magic bullets. Don't over think it.. Well-balanced diet that supplements your soil as it loses amendments... some beneficial microbes, some humic/fulvic acid... but much more than that and you delve into the realm of speculation and magic.
everyone wants to treat their girls special.. and there's a lot of marketing nonsense to manipulate that urge. (for every garden hobby there is.. not just marijuana)
