I'll keep a closer eye on it then.I can also easily dissolve calcium phosphate or calcium nitrate, of which I have both, into RO water.
The precipitation happens when magnesium enters the picture. Separate they all seem to dissolve easily, but when they are combined a chemical reaction occurs and something along the lines of gypsum precipitates to the bottom.
I could and have added nutrients individually, but it's much more work. I like less work. Take the extra time needed, divide it by the cost difference between Calmag and the separate ingredients and I guarantee you wouldn't work for that wage. This, besides the fact that the Calmag Plus is just better. Perhaps they should rename it Braundo...
I mixed up my first batch of nutes with it on Monday night, and didn't notice anything when I added my epsom salts. But I wasn't looking for it either.
Nice thing that surprised me was when I went to check pH 9 hours later, it was dialed right in a 5.65. And 24 hours later it had risen to 5.7.
