Charging coco

How much nute's should I add to charge the coco.

I have the canna line up and floranova bloom, maxi bloom and cal mag+.

This run am only doing the canna lineup, calmag+, with canna coco and ro water.

i always do an equal volume; 5 Gal of substrate, gets 5 Gal of solution. I set up a recirculating system, pumping the runoff back though the substrate. This might be overkill, but i dont mind.

I also monitor the change in EC, going in and coming out, (pH too) this makes it pretty much full proof.
