Hey Craven,
I always thought that Coco was Organic bro, i think it more depends on what feed you use that defines weather Its 100% Organic or Not! I believe the PH for Coco is more like a soiless mix's/hydro, 5.5 - 6.2 would be appropriate i believe!
Are you thinking of running Coco in your Water Farm style Rig? I'm thinking of going CocoNuts on my next run too. G'Luck Buddy!
Peace........Scroger!
