no,do not clone while in flower,i did this not so long ago and my results were0%waste of time,just wait for the mum,the right lady will come along some day!!ps..NOT a good idea to clone a flowering plant,kinda defeats the purpose.......your taking a plant and reversing its natural cycle(birth,veg,flower,death).much stress on the plant,lost your fruit,and probably gonna have slow rooting clones or non rooting clones.much better to grow out a nice bushy mother and take clones @ your convience,or clip during veg time
