She should be photoperiodic but as they are crossing autos to photos to obtain the quick/fast version, you can still have some autos genes on some individual.
The opposite is happening sometimes aka an auto flowering strain that needs a 12/12 light schedule to bloom because it’s a photo.
In your case don’t worry because the plant is not flowering but only showing sex by pushing some pistols on the bases of the stems but not on the tops parts of the plant
