I still do consider myself to be as organic as possible. Technically FeEDDHA is non-organic, or any chelated iron for that matter, but in all aquaponics, it’s required. I also supplement micronutrients with non-organic solids, like PEX piping copper rings and galvanizing steel.
I don’t consider an isolated study of foliar spray to 3 plants to effect the “organic-ness” of the entire garden, even though using the same water. Any water access was sealed off.
