I don’t know what to think of this. One of the smoothest smokes I ever had is my Wicked Widow and that is supposed to be a White Widow S1.
Certainly there are strains and even plants from a specific strain and variation among them. I have come across at least one strain that I could not smoke (Tokyo OG) It was a medical dispensary purchase. Grow methods and media matter.
If you got it as a cut and it’s Mom had PM I guess it will also be present in the cuts since PM is systemic (or so I have read anyway.)
