So, not to steel your thread, but does anyone know what the symptoms and/or effects of this (rather slight) imbalance in these two major ions would be?
Randy, I've seen your graphs, and agree the shift in concetrations will occur, but do you have any discussion(s) of what the actual efrfects of this shift will be in any of your many excellent documents? Or, any thoughts on this practice (using Mg sulfate alone)?
There is quite limited info in this area, so it may be OK, but it is a risk of being unnatural and so of causing issues that we cannot foresee.
