there's no unique product out there. big bud definitely didn't do it. you don't just add "something" and magic happens. This stuff is made of the same old shit over and over again. i bet one of those below is simply monopotassium phosphate. you can buy a generic of it and it will perform just as well as the marijuana product with the sugary cereal-esque label and marketing BWAHAHA. If it has a fuckin cartoon on it, how can you respect it? it's like little kids in the cereal aisle wanting the prettiest box.
This stuff is made of a few different options of ubiquitous commodities. Read the ingredients. don't overpay for something that is molecularly the same as a cheaper product. There are no tiers of ammonium nitrate or monopotassium phosphate, et al. Magnesium sulfate is always magnesium sulfate no matter what the label and price says.
fertilizer should not be a major cost. if it is you are being duped.
track what oyu feed. push boundariees of each... you also have to worry about stimulative and antagonistic relationships between these nutrients. These companies rarely produce ph-balanced products and i doubt many of them hire a chemist at this point. BWAHAHA.
