m0useanswered grow question 2y ago I don;t know if I fully understand the question. I think your asking is it ok to take clones from smaller branches that are all ready in flower?
If so, yes you can take clones from a flowering plant, its not the best idea as it can shock it, more ideal is clones when it is vegging. The clones you do take in flower will need more time to reveg. This process causes some weird growth on the plant but it can be trimmed back once it settles into its new form. Make sure to give them 14+ hours of light to make it reveg.
Alternatively you can try and let it develop roots while under the flower photoperiod of 12/12 then once roots established switch to 18.6 and reveg it. This is a bit less shock to the plant but will take longer overall.
Good pick of seeds on Humboldt Seed Org. I liked their stuff. I guy a raspberry diesel from them and all the seeds failed so was upset about it but still have a few of their other genetics.
Good Luck!
