Who are speaking about magics ;-)?

I know there are to many variables, but I think is quite easy, at least on
my case. My water is hard about 15 Gh, sure is not a measure of Ca, but  I
will have so bad  luck all these hardness is produced by Mg?. Why These
retorted grows remits only stopping K dossing?.

I dont want to polemize, Tom, but my only variable where always K. I,m not
telling thes effects are "because" K block Ca uptake.

Other parameters? OK lets go to make one Hypothesis but ¿Which other?¿Where
do you thing will be the explanation?

I want to say I have no problems, when "I" have distorted growings, I reduce
my K dose and thats all, everythink goes fine but I would like to know why
