No sign of flowering, see close up pictures

Hi there! Yes there is no sign of flowering yet BUT the bigger they are the bigger the yield will be! You still have some room in the tent so if you are not in a hurry I'd say give them week or two more to grow and see if the flowering starts by itself then. You will have more buds in the end with this. If you really want you can flip the lights to 12/12 to promote flowering but your yield won't be as big as id could. 👌 Hope this helps!
