Ok so I am growing a couple autos in coco coir. I'm using PureBlend Grow Pro and I think my coir is becoming too acidic from these PureBlend veg nutes. I have CalMag (actually, CaliMagic or whatever, but essentially the same thing..) but I haven't used any of it yet.
I told my local hydro dude that i am growing in coco with PureBlend nutes, and he recommended using the CalMag. My question is, does CalMag buffer your substrate's pH, as well as (obviously) deliver Ca and Mag? Will it significantly buffer my coir's pH, or do i need to invest in some pH-up?
Is there any recommended ratio of PureBlend-to-CalMag?
Thanks!
