Your plant is in good health therefore you could clone anytime now. Any lower sites would be preferable as you want to keep prime bud sites intact. I recommend a rooting gel for you cuttings, rockwool cube in a cloning tray/dome. 👍 Kush all day!
Hi there @CaliforniaOGkush Nice plants mate !! You should go ahead and clone those girls now.
Simply remove the lower branches as cuttings as they will be getting less light if kept anyway.
5 inches is about spot on give or take an inch or three 😃
Best of luck I love my OG kush 😍
