Hello ! Well if she's swelling up even without drinking then I woul not worrry about it and just wait for the soil to be dry before the last watering , that mean you have still nutrients in the soil and the plant are using them while soil is moist. She's nice but for an autoflower under a 12h light schedule you should go to week 12 at least and check the trichomes with a magnifier before harvest. I hope it will help you 😁👍
