well the "NPK" should be on the bottles just go with the recomended doses & ya should be fine.
I also use the big Bud and the vitimins .
I rescently started useing alaska morebloom just cuz the NPK is 0-10-10 compared to the iguana Juice bloom I was useing witch was much lower.
but that don't mean one is better then the other one is fish the other is guano worm casting and bird crap and bunch of other stuff.
so I just figure bigger number, bigger buds. but I ain't no nutrient scientist just trial and error buddy, trial and error
