Hawkbo: CookieFi IX x7 Photoperiod Regs

I wish I remembered when I flipped these I wrote it down somewhere but forget. The big one got a late transplant into a 5 gal bag cuz it was too top heavy. The frost is startin to come and there are light purple outlines around some of the sugar leaves. The 5 smaller ones are taken longer but are healthy atleast. I took a cutting of the big one a few weeks ago to keep as a mum. I'd like to have a cutting of each but idk how to keep them all without having to take up too much space this is my first pheno hunt any advice would be great from some of you with more experience in that area especially since I have more strains that are still seedlings I'd like to hold on to as well
