BioBizz does not work well in coco. This is from an e-mail exchange I had with the biobizz folks in holland:
"Bio-Grow, Fish-mix and Alg-a-Mic are not working on
coco. This is why we do not have a coco grow schedule. It is nice of your friend
to give us a try, but for sure he will have trouble. He needs a coco A+b
nutrient as a basis, and he can use Bio-Bloom, Bio-heaven, Top-max and
Root-juice as additives. A shame he did not know. Even with an adjusted pH
level, he will not arrive at optimal yield. Sorry to be honest about it!"
Just my $.02
