    NPK ratios best for flowering? Dutch Master Potash + for flowering?

    So basically I've got some bloom booster and wondering what you guys think of it. 4% Phosphate, 9% Soluble Potash, .003% Boron, .00007 Copper, .00007 Manganese, .00007 Zinc. Would this be any good in flowering stage? Any advice would be good :)
