I like to know all of these little details so i keep them in a notebook.
Did I say that? That is not what I meant. CalMag plus is what I recommend with every water change (but flush) as preventive measure for those of us who use RO water.

The Fish shit is extra Manganese when you have a problem like Marc was talking about. If the plant needs a shot of Manganese only that is a cheap source.

I would not use it all the time unless you are growing Organic and then it's only a supplement you add to your other nutrients.
