Is there some way to grow completely organic with coco, or is coco best left as an ammendment when growing completely organic. As I understand that bat guano, etc. will lock up the soil. I found this by Suby:
"Here is the gist of what's fucking up in your grow, coco is a shit medium for a guano grow. It initially releases K bound up in it matrix (K+) then gets bumped for Mg+2 ans Ca+2 which then get bound in the matrix.
Canna ferts are designed for coco and you'll see they are very high in K and in Ca and Mg, these 3 elements are the trickiest elements to get into your soil throughout the grow so if I had to guess your def. was calcium and to a lesser extent magnesium. While coco buffers very well, almost too well, it takes on the ph of the fert solution too quickly that's why humic acids are in the Canna stuff to buffer the ph. Dolomite lime would have helped for ph and Ca and Mg, using calcified seaweed gets plants extra Ca but can be tricky to find. Nutrient profiles for coco are best suited to all in one ferts and usually not the 100% organic kind, a blend like PBPro with the CalMag formula added will yield very good results but not 100% organic."
Suppose a few compromises could be made for a not 100% organic grow with coco such as PBP Pro with its calcium carbonate (chalk) and other vital immediately available nutrients in balanced ratios. Not sure if just because of the calcium and magnesium carbonate that it is not considered completely organic.
