Haven’t checked into these guys in a while, though I did pick up some of their cal-mag since it’s basically the only one around that doesn’t deliver the cal through nitrate. Helps that it’s organic too, which presumably is how they do it. When I first started talking to them they were also trying to test out an organic AIO, and I was about to test for them until COVID hit and their organizational skills went to hell in a handbasket. I guess it didn’t work, since it’s no longer mentioned anywhere on their website. 
It sounded like they were trying to make it hydro-compatible, probably why it didn’t work. We’d gotten as far as the consultation and he’d offered 50% off the product during their testing phase, then told me he’d get back to me once it was actually available to ship and here we are 3 years later.
