The new buds are because the plant is still going. The 70 days the breeder said is not an accurate reflection of actual finishing times most strains IME need three full months from seed to fully mature. The NL auto I grew took the full 3.
So you could pull it now but I would not. I would let the plant finish, there are new capels n pistils and it's caylexes were still flat rather than folded, so it doesn't look done to me. Are the buds hard? Check out the "is it done" thread over in the harvesting and curing section.
