I can see white pistils on your plant and no signs of male pollsacks, so it's definitely a female! Since autoflowers are a mix of photoperiod and ruderalis, it sometimes happens that the autoflower-genes do not prevail, which means this is unfortunately a photoperiodic plant (if u dont see any signs of flowering after like 5 to 6 weeks, its definitely photoperiod).
my suggestion: keep the plant small with low stress training, wait for the other autos to finish, then give the photoperiodic a bigger pot and fill the whole tent with it and switch to 12-12 and harvest 8 to 10 weeks later again :)
happy growing <3
