Oops! I typed that out wrong. They add Power si (silica) and a cal mag (whichever brand you prefer) with it.Powersi is a calmag supplement?
I’ve seen people use it with almost every other line.Does anyone run Athena pro line with power si?
CalMag supplements exist because you could have high levels of Cal mag in your stock water (ie hard water/well water) or at the other end of the spectrum if you're using RO water or have soft water, then you need to add Calmag.I’ve only used the GH trio line and I found I had to add additional calmag to it. With the floraflex line do you have to supplement calmag to it as well?
