You can still clone a flowering plant fairly easy, its not very recomended but managable. My freind had to do it and he took 5 off a flowering plant that was 5 weeks in and they turned out fine, it just takes a little while longer. Cloning isnt too hard to do either, well ive never had any major problems. As long as you take care of them they should good.
Well i hope this helps.
