Your right that EDTA is not organic but to go so far as to say it will effect yield is bull shit! Personaly I would be more worried about arsenic as it's in everything.the point is EDTA is NOT ORGANIC and it's toxic to your beneficial bacteria. I don't care; use it all you want, but you're not organic, you're "organic based" if you do. in a finely tuned FULLY ORGANIC system, EDTA will drop your yeilds through the floor. so keep recommending it's use by all means, but don't tell people your product is organic cuz it ain't. I learned all this from the Cultivation Editor at Skunk Magazine so if you take umbrage with what I'm tellin ya, take it up with the Rev.
By the way one of the most use products is Cal-Mag and it has it, but I don't see anyone complaining about it or their yield.
Some organic compounds have the ability to form complexes with metal ions. In which metal ion is held fairly tight chemical bonds. The complexes form either linear or ring shaped, in which complex is called chelate (derived from Greek word meaning crabs claw). Naturally occurring compounds acts as chelating agents such as proteins, peptides, carboxylic acids and amino acids. The EDTA (Ethyldiaminetetraacetic acid), also used to chelate metal ions. The effect of chelate increases with number of chelate rings. The ions from EDTA completely wrap up the entire metal ion from 6 positions. The complex that formed with EDTA will be greater than amino acid complex than nitrogen donor ligands or four carboxylic ligands. In fact iron appears the most particular element to keep soluble with pH. The EDTA is a great stabilizing agent that keeps iron soluble in pH fluctuations. The unusual property of EDTA as a chelating agent is its ability to chelate in 1:1 metal to EDTA complexes, which is a very strong proportion. From Technaflora Plant Products, BC Boost, Awesome Blossom, Magical and Root 66 contains Fe EDTA which ranged from 0.05 to 0.1%. As EDTA is synthetic product, it can be used for synthetic products only. According to OMRI regulations the products that contain EDTA will not be certified as organic product.
