Cool, Just wasn't sure if after 3 weeks in the cloner plants would be ready to take cuttings from. And on the same note I was worried about taking cuttings from the ones just put into flower, as I wouldn't want the plant to focus on repairing where I cut as opposed to focusing on bud production. But I would imagine it takes a little bit for it to go from veg to bloom, so during that time would be when it is healing itself.
Take clones from the lowest possible branches that are as close to 4" as possible. Stinks cloner really has 100% success I have even taken some from my finished plants..the lower buds little nothing popcorn that doesnt even amount to a good toke.... they took longer but they rooted and basically saved the genetics I wanted. Once the plants are in full bud production you are right to a degree. If you take certain little branches they dont really regrow them they focus the energy to where you want it...making flowers.., but that in itself is a lot of info to learn about where to clip when and why.. The transition takes a couple of weeks for them to shift from growing ... to flower. Its not going to effect it at all. Follow Stinks design to the letter while you learn the "WHY" and by the 2nd or 3rd you will feel like a pro, but all the years Ive done this i learn something new all the time.
Just a little added info little off subject....buy neem oil and lady bugs...the lady bugs will eat mites and many other unwanted bugs and the the neem oil is an organic way to prevent larger leaf eating bugs as well as white powdery mildew.
