I have to agree with Hermie and manufacture. Put some nutes in the water and watch it stablize. Kind of answers some of my questions about chasing PH. The higher my PPM's with 5 ml's calmag the more stable while light nutes and calmag I'm chasing it down. They put something in the water here so the marines don't go crazy when they come back and it kills plants. LOL

I will try too backing down on the calmag. Might just save a plants life.
