Diamond K Gypsum - Solution Grade

Following up during a phone call to BAS, they suggested I try this Gypsum to add Calcium to a mix which was my third run in 15 gallon containers. I had "re-amended" with a combination of Coots mix and Oly mountain plus added worm castings when I transplanted. But there was signs of yellowing and overall "exhaustion". Adding the Diamond K definitely helped green them up after two weeks or so (using a blumat system via top dress makes a bit slower intake/uptake).

So great! Instant feedback with plants!

Amazing product. Super easy to mix. Plants seems happy immediately

Plants thrive

First off, what a deal. Half the price for double the weight when compared to Amazon. Diamond K is what I've always used for mycology but never for my plants. I've since started adding it to my soil for the calcium and sulfur and my plants have been loving me ever since.

SB; I was fighting a mystery deficiency which turned out to be a calcium deficiency. Ever since fixing that with some rock dust and gypsum, things have been smooth like butter.
