Hey Growmie,
Take it from someone who only grows autos, this is an autoflower, and yes she's beginning to flower, now if this was a photoperiod plant you would certainly need to change the light schedule to get the plant to start flowering and yes normally when you begin to see pistils this is the first sign of the flowering stage. Hopefully this was helpful and remember ... "Happy Growing" and "Free your mind one puff at a time"
