Stoping flower and geting taller

Cant really see anything with those lights on

It appears that you may be giving these girls too much Red light. It could just be the photo, is there a good amount of blue led in your lights? Too much red light can cause stretching but typically not late into flower. Too much red during the veg, pre flower and first two weeks of flower will cause the plant to stretch and become too lengthy. If your light is balanced then I would check the EC and Ph of your runoff and post that so we can get a better idea of what could be causing this! Also possibly a picture with the grow lights off and your camera flash on? This helps a ton!
