Well the purple dude is either male or hermie no doubt about that, female formations are noted by the white-translucent whisps coming out of the pods. These pods are male, they open teeny little flowers to pollenate the females via the whisps. some people call those pods bananas, or nut sacks, personally I can catch them when they look like baby grapes on a grapevine in early may. You know when you have ready to smoke bud, and theres orange or red or brown hairs on it? those are what the white-translucent whisps turn into when they stop being sexually active and dry out, only female plants have those. I'm not 100% on hermies, but that plant definitely has male aspects, I can't see any female.
it seems your WW plant is far enough from being mature that it won't be pollenated if you kill the male in question.
and 50 Fahrenheit/ 10 Celsius are the magic numbers for purple buds! I did not know that applied to males though.
