def. a male.... my suggestion. while on 12/12 (dunno how it works for autoflowering plants), every hour of light u give it, give it 15min of dark, and vise versa during it's night cycle. i did it, shocked my plant into being hermie, and then chopped off all the pollen sacks.
Don't throw away male plants imo, put them in a seperate area, and let them grow. Save 'em for hash and the stems for tea, and do this... grind up fan leaves and put 'em in a bottle of vodka in the dark for 3 weeks, makes a drink called green dragon. vodka + thc! only take 1-2 shots tho, cause it'll hit you hard
