This plant is re-vegging, that means that the plant had been triggerd into flowering first by giving her more than 10 hours dark period per day. And after she got triggerd into flowering than the dark periods got disturbed and got shorter than 10 hours so she goes back into the vegging stage.
So basically she is in the vegging stage now and you need to give her 12 hours darkness if you want to turn her back into flowering. Just switch her to the 12/12 schedule and enjoy the rest of your grow!
