Does High Number P Fertilizer really work?

[NYCorchidman]

I have read mixed stories, but are there any good articles or study to back it up?

I always thought it was just a marketing gimmick.

The basic knowledge for many is that N is for the leaf and P is for the flower, so the higher number of P equals more ( or better) flowers, which I don't think is how it really works.

Or is it more of the ratio of N to P that bring out results if any at all???

I have always used a balanced fertilizer and things are all well including the flowering department, but I'm just curious as it bothers me every time I online shop and see these "bloom booster" products.

Any good info is appreciated.
