You can easily take cuts from a flowering female for the first two weeks of flowering without harming overall plant/bud production.Me,I like to take cuts1-2 weeks before flower.
What I do 1-2 weeks before I switch to 12/12,is I skip a veg feeding or two and give a light flowering fert dose (P and K promote root growth and nitrogen just slows the process down for an unrooted cut).
