this mandates more nuance IMO "when it comes to things that are molecularly consistent, generics are like Rx generics -- the exact same thing. calcium nitrate is always calcium nitrate. magnesium sulfate is always magnesium sulfate regardless of branding... a rose is a rose is a rose... The ingredients of cal mag products are probably very similar if not exactly the same. even if they use a differen molecules to deliver each, ca and mg, the resulting level of Ca and Mg provided is all that matters for the most part."
know your guaranteed analysis and understand how the industry works. AN is nothing but supply chain mgmt, when a metric ton of a single salt comes in dirty with heavy metal poisoning by the CCP, AN is typically one of the first to be aware. further, your NPK values are not the 'go by' that most think they are, it is a regulatory metric..........
you may have X listed in your blend, even in the guaranteed analysis, but that doesnt imply absorption. example with you - your special K cereal has iron, but not the kind your body will ever absorb ever.... you poop it out or you can oxide then recover it in a lab (to prove it was never the type your body could absorb anyway lol)
lots of things sound good but fall apart once you know better. kind of like finding out your favorite youtuber isnt actually an expert, because the 4th wall broke on a topic you actually understood before their content.
I say steer clear of AN, but only because of their recent changes in formula. some one-offs are solid salts only, and unless you plan on taking a 500mg pill and crushing and cutting it to does out properly from a 55 gallon pill, with your 000000015 TDS RO water, then AN prolly isnt for you moving forward. anyone comparing a jack or yara AG quality salt to AN's supply chain is wildly misinformed, and would be the types to think their special K is giving them iron. AG salts are notorious for contamination (because it doesnt matter over a 500000 acre field of corn, but it does for your flowers). We are growing medicine. Medicine from a plant that is so good at picking up heavy metals, people use these plants to literally mine metals from the ground - just trust your source for inputs.
