Blueberry or Critical Purple Kush?

Just some light defol and watering while mum's in hospital so the girls haven't had as much love over the last couple of weeks. Hopefully if mum improves I can spend a bit more time with the girls to give them some more nutes, but they should have enough in the soil atm :) Was gonna switch her this week but I haven't sorted out the auto switching of the lights to make sure I'm keeping to the 12-12 and not too keen on having my first grows go hermy on me :)
