Different K's will play with the teripinoids which will change the spikes of naturally occuring flavors. Why add fruit juices,sandalwood oil,molasses,etc unless you were stuck with some Iowa dirt weed for genetics.
I used some DAP last run which made my BP go from a chocolate hash/coffee flavor to one of a chem/diesel. I did not care for the change but the patient/shop did. Suerte JK
