I would agree with @Andrew H and up pot soon. I would think pinching off a root creates an energy focus point the plant has to repair and not energy towards growing. I would let nature take coarse and the light and air will dry it out and fall off naturally. With that being said depending how long you plan on veg adding the flower period I wouldn't want to risk root bound during flower. Just my opinion.
