I don't think the PureBlend is OMRI listed organic, but I consider it organic enough to call the product organic. The others, I'm not even close to knowing the answer. I'm gonna say negatory on the sweet and calmag.
Beauty of growing a controlled ag product is that you don't have to submit to inspections and permitting to call your shit organic... if it is, it is, and if it isn't, USDA honestly doesn't give a shit. lol. We're on an honor system, and I like it like that.
