By Blue do you mean the livers/blues etc?
I am not great on 'street names? Basically its always been called Blue/Blues Chef Blue and some guys call it Livers but Its like cheese imo, slightly bolder deep smell, musky even, it stinks like fuck anyway and ain't viney? But it might be Timbucktoo for all I really know lol
Anyway I grew a male Jack Herrer and we did a few seeds on one of these Blues or whatever it was, it was more as a bit of fun than breeding? Popped 24 and they were all ok except this one which is mad potent, I assumed all seeds off 1 plant would be the same?
This proper knockout bud is from them seeds, I grew it when I got out of the grow clinic in May 2015 but all I have left is a stem near the bottom trying to get it revegging, its not looking great...
