Why do you want 24-8-16? If its for pot plants it will cause deficecys. The recomended NPK for marijuana is 10-10-10 for veg and 10-30-20 for flower. Coco is a little different but not that much. The mix you want comes out to 30-10-20 or 3-1-2. BC Pure Vida grow is 6-4-3 and AN Monkey Juice Grow A&B is 6-2-3 but thats the closest I can find. Good Luck!
