I'm running jacks 321.. the NPK is 3-1-4, its killing any high P bloom ratio I have ever used & I have been at this for over 20 years, plants are soooo much healthier its ridiculous. not a single negative & tests show it out THC level's the same strain grown with high P bloom nutes, bloom nutes do add mass 100%, they will out weigh low P grown buds but the quality is also lower with the high P bud.. Ive seen several tests.. High P is a myth, the highest P I would ever run is something like 1-1-1 or 7-7-7 or 20-20-20, whatever. and then I would boost the K.
