The other thought is that you may be closer to being done dude then what you think. General rule of thumb is that when 50% of the hairs have crisped up you are at the point of being done. This is only a general rule and checking the color of the trichomes is always the best, but if I am right, by your pics you appear to be more like 75%. It is a balancing act because if you leave the buds too long the thc in the flowers actually start to degrade, producing a less powerful smoke.
My auto assassins which are only five days behind you are not even 10% in hair colors yet, so I know my girls are going to take a full 65 days to finish. With autos, or any strain for that matter, it can vary for finishing times. Growing conditions can also play apart and since you have such a high amount of light per square inch in the pc case you could easily have shaved days off compared to smaller bulbs on the same strain. You could always check it the most beautiful way, which is snip off a small bud, dry it for a day and smoke it. If you enjoy it then, you know it's only going to be better dried and cured. Peace dude
