I find cloning about 7-10 days into flowering works best for me. I've had problems rooting very small cuttings but if I let them stretch for a few days after switching to 12/12 they seem a lot stronger and I have a better success rate. If I go much longer than 10 days after flowering I find that it's too much stress as they've gone too far into flowering and I more clones too. JMO
