Ah, I got it now! That's fine. The reason that it's finished already is because it probably got far warmer than 70 degrees during that blow-off time. It's not unusual for active fermentation to finish in 1-3 days, especially if it's warm (above 70 degrees). In any case, wait one week and then check the SG if you can't stand to wait two weeks.
At two weeks, SG readings can be taken three days apart, and then the beer bottled if the same readings occur.
