I agree with Cort if you are serious in looking . Especially with males. I would not take the cuts early,no need to stress out the plant. Around flip you need to clean up the plant and get it ready for flowering.Those branches I removed for this is what I would use for cloning.I use wire ties in many colors to mark the plants, they can not fall off or writing smeared. It is easier to pay for a known cut,but pheno hunting is fun and more personable. I must admit I have really fed my ego enjoying a smoke that only myself and few friends have tried. But I must warn you I have crossed the smelliest, thick stemmed, stud to the knarlist known female I have had and the progeny was weak assed worthless crap. Some experiments blow up in your face, some lead to simple but great things like velcro. Then again you might have the devils luck and pop some bagseed and start another line like chems.
And to Seamaiden I must say you should clone some flowers. I do this on my quick cloning varieties.Most of my girls takes 3-4 weeks normally to get out of the cloning area. My BP would take 2.5 months for this, but the effort was worth it. Where that bud is will pop out about 10 branches. Great for trees or backyard plants.
