Hey Roasty, just going back over your thread and caught this post. I read a study about a year ago that analyzed many plants for nutrient uptake, including cannabis, to see what each flowering plant was using the most at harvest. They did this by weight. Across the board, nitrogen was still being used the most, even in flower. A close second to N was calcium; phosphorous and potassium were much less prevalent. Since then, I have started adding more dolomitic lime, and only dry organic bloom ferts in the bottom third of my pots. When using straight coco, or a coco/perlite mix, I added 2ml per gallon to every other feed. It has worked great for me. Maybe this will be of use to you brother.
Also, I can't wait to see the candied cured buds from that monster you grew!
