No one very slow flower stage.

Hello, I'd say give it a little longer to see if it will start putting out bud sites and pistils. Maybe its internal clock is off and will flower late.. Otherwise it is possible to get a photo period in with an autoflower batch. If the plant doesn't start flowering soon you may need to initiate a 12/12 cycle to it and see if starts to show bud sites, then it'll be pretty obvious that this plant will need to be given the 12 hours of darkness each day if you have somewhere it can go.
