many thx for a good post...
ive been running coco for some yrs now and use my own fert formulas mixed from yara salts with mostly excellent results..
im now trying to mix my formulas to achieve the best Ionic Balance but have some comprehension issues haha
i have noticed running 0.5 EC water like you also mentioned you will always have to fight against the buffer / alkalinity nothing new
i know this will sound strange but here is how i go about it:
I ph the tap water to 4.5 to break the buffer and alkalinity.
Does this make the Calcium/Mag unsoluble, would they precipitate?
but when i bring it back to 5.4-5.5 with adding a touch of K2SiO3 and some more tap .. will they be in ionic form again??
i then add my nutes and have a stable rez
i know the the easiest would be to get RO water but thats not a option right now...
so anyway my rez stays stable so thats ok
so my question would be is my water completely out of balance?
the big amount of added OH- by the P2O5 will be balanced out with the nutrients no?
i guess the only way to find out would be to calculate it to be sure
