I agree with BluntZilla, those numbers are INSANELY high and I would/could not recommend ANY product with those numbers. Something like 0-13-15 is all that is required and then only in small doses. Any decent/proper Cannabis "bloom" nutrient will have P and K in suitable quantities, so there is no need for extreme products like this. I usually give only 2 doses of PK booster, (an organic 0-13-11), one at half strength about two weeks after flowering begins then another, also at half strength, about mid way through or roughly 4 weeks before I expect them to finish. Using this sort of product many, many years ago thinking it would be a "sure thing" to get "super buds", I actually found all it really did was give the flowers an awful metallic taste, even after "flushing" for two weeks before harvest and vowed never to use those sort of products again. They may have a place in growing giant pumpkins not intended for human consumption, but as with most things in life, there ae no "free lunches" and bombarding your babies with over the top products lie this will not give you a short cut to super dope, or make up for other deficiencies or problems elsewhere through the grow cycle.
Be afraid, very afraid of these "Frankenstein" products. I wouldn't even use them on my tomatoes !! Hope this helps,..... Organoman.
