The terpene profiles are probably changing do to environment, Nutrients used. I have read that one of the heavy metals or minerals if low constantly (I think MG or sulfur) Will cause a change in smell and taste. This is just a guess from what I have read. With mine there is no Sweet, Pine, Fruity aroma's or tastes. Its mostly a sour choc/coffee diesel chemy dank with a slight pepe lapu..I have read a few report Soap, Fruit loops, perfume, Sweet smells or tastes .. I know many can smell things alot different then the way I smell things. So its really all subjective.. If that's what ea of us smells it cant be disputed.
