Yeah definitely got some time to kill and sativa dominant auto flowers can take a minute compared to indica dominant, I just cut down a blackberry auto and it was rip for the pickins at exactly 8 weeks but I've had sativa dominant auto's in the past that has taken 10-11 weeks to finish, I dont know if sativa is exactly what you're growing but it does have the characteristics of one and would explain the extra long flowering time, another month would be about what i would wait, that would put ya at 11 weeks and hopefully some fire ass smoke.
