Canna coco recommends pure/clean "0" ec/ppm water as a base. Canna is silent about supplementing. And if one does not the nute levels have to be sky high just to get to the recommended PPM range. It is like a piece of the puzzle we are left to figure out.
Somewhere in A & B there is both cal and mg.
In an effort to cut down on RO decided to blend purified tap water. Local water is hard at about 300 ppm and 7 PH. Both drop marginally with gravity water filter.
Last week used mid-200's. Now, worked the mix down to pre-nute level about 150-175 give or take a bit. That is in my case--3 gallon RO to 2 gallon filtered.
PH takes more acid to bring down from 150 ppm with filtered/RO water than just RO with cal/mg supplement. Leads me to believe that the water with the natural conductivity seem to be more efficient and plants show no deficiency. Shall see how flowering needs go and report back.
Put this up just in the event that the cal/mg issue might have a better solution without having to initially dose with cal/mg. Us coco growers are always batting cal/mg issues around.
Cheers
