Girls look great, but honestly they look like they have at least 4-5 weeks left.
Keep your flowering nutrients to it and make sure you have a small 60X adjustable micorscope. can pick one up on amazon for like $15.
When you think it's close, check it. take a little snip, 1/4 of the tip of one of your upper cola leaves and check, Your Trichomes should be at least 100% cloudy, for a cerebral buzz, and then willl start developing amber trichomes, body buzz.
When they are all cloudy and going amber, the sacs of the hairs will swell, causing massive growth on the buds,
Currently they are still producing a shittonne of white hairs, with little sacs on the bottom.
Unless your trichomes are 100% cloudy with some amber, I would let it go. When the sacs of the hairs swell, you will see your whole plant jump up in density and size, but don't cut them short of their nutes untill at least 1-2 weeks before flush. I would get the nutrients back in them, depending on trichome color, an cut all of your large fan leaves off. If the base of the leaf is not imbedded in the bud, remove it, as it will allow more nutrients and light to get to your bud. more light on the bud = more size density and trichomes. Best of luck.
