i am wondering just how to use the npk numbers to get the nutes that i want. example: lets say, i want to feed my plants an npk of 5-10-7 during early flowering. how can i get those numbers? do i settle for close? exactly how do i use the npk numbers ? i understand that the numbers tell the percent of each n p and k. should i mix several bottles?
