I have seen inconsistent information as to whether it is primarily phosphorus or potassium that aids in flower and fruit production, but have always been under the impression that it is primarily phosphorous that does this. I have heard in the morass of available information that potassium is generally required to aid in nearly all plant processes, including flowering and fruiting, but also green growth. I'm curious to know what other people have heard about this.

I agree that the brand name of a fertilizer is totally irrelevant so long as it has the elements that you need, and you are applying it properly. that said, i primarily use a nitrogen high osmocote, supplemented with a nitrogen high fish emulsion. if i want something to flower i'll lay off the nitrogen and give a high phosphorous feed.
