Probably. I have no experience with the CoGr line up but i imagine that CoGr buffering solution is largely comprised of calcium nitrate, magnesium, iron and fulvic acid.
"Thanks for the question. We do pre-buffer the coco. This is done with many different ions that, in this case, do not function as a fertilizer but a way to buffer the pH and ion give off of coco as it degrades. So, yes we buffer, no we do not pre-fertilize, and the ions you asked about are in the mix with others."
That's what Canna Said. Great info lol.
