Sorry to burst your bubble but it's one of thousands of mineral salts and there's not a thing organic about it one little bit.Epsom salt is an organic magnesium nutrient.
I may be OKed for use in organic growing but it's not organic itself. All organics contain carbon and MgSO4 doesn't have any.
It's,(shudder), made of the same kind of things that all those so-called chemical nutes that come in bottles are made of. That's why I laugh at organic zealots that freak about using bottled nutes. Bottled nutes are cleaner than organics when it comes to heavy metals and other contaminants so it's all a matter of taste and perception.
Epsom Salts is great stuff and I use lots of it myself in hydro, soilless and the semi-organic growing I'm into these days.
