Anyone use hardwater nute?

[Rimbaud]

I was poking around and spotted Flora Micro Hardwater anyone using it or something similar? I am probably going to use a DWC system (just two buckets in a cramped spot, nothing special) with the gh flora 3 part and this seems like something that might be nice to keep on hand if i run out of RO. Any thoughts?

I use Hardwater Micro in my Hempy SOG.

It works fine for me, I have hard well water.
