Takashi Amano already knows this and he isn't concerned with being called "EI" <-- he fundamentally knows that EI is a concept and the numbers are meaningless. EI is about more than fert targets. It's about how you run a system with datums, flow management, saving money, dry salts. ADA is about a system too. I own all of Amano's books and admire him for his work in this hobby.
People who build these systems and understand them laugh and shake their head when they read about tunnel vision on nutrients. There is so much more to this game. To be honest - there's too much to understand ... and when you realize the interconnectedness off these systems you realize that we know absolutely nothing. The only way to make any headway is to consider it a dynamic system of finterconnected stuff and see how that stuff MIGHT interact under a series of constantly changing parameters.
Tom Barr knows that plants primarily get their nutrition from roots. He built EI for fun. Look at his tanks ... they use soil. And the inert ones? That's for fun and curiousity. ANYONE who scapes inert ... does 3x weekly water changes and resets to datum and dose whatever fert is sponsoring them.
Amano was curious. He built an empire and sold a system that works so people don't have to think - they can focus on art.
Literally, we get curious and want to understand why ... most just want to grow nice plants and are cheap. No one gets into dry salts because ADA doesn't work.
The plant needs to be fed ... so feed it and focus on the big picture: this is an ecosystem.
Dennis Wong exploited the need - people struggled with EI because it is hard mode because of how hard rich water column dosing is to manage -- and ADA is expensive.
Everyone knows ADA is rich dosing - but ADA without potassium doesn't work. Buy his books ... you will see every single parameter on every single tank.
