Out of all the different nutrients and nutrient companies I've researched Advanced Nutrients is the only one that says to use a bloom formula with twice as much K than P, so in other words the ratio of P (phosphorous) to K (potassium) during flowering should be at least 1 to 2.

For example, they have a product called Hammerhead Flower Booster that is NPK 0-9-18.

Does anyone grow using these ratios?

All of the nutrients I've tried are never near that, and are more along the lines of an even amount of P and K, and I'm having trouble getting big fat buds, mine are mediocre.

Is the key to big fat buds using more K than most nutrient labels say to use?
