You're all confused though. Nothing you say makes sense it doesn't work that way.
You either take it out of 12/12 and never get bud and it never dies and can be a mother, or you leave it on 12/12 get tiny buds and it dies. You probably won't make it too long if the pot is so tiny you have to water constantly anyway, you'll end up with root rot or accidentally let it go too dry and die. Death will be coming soon either way I'd guess.
Lastly clones are best off full size healthy plants with big leaves, spindly little things with tiny leaves are going to be a whole lot harder to clone successfully, I don't see you pulling off any cloning if you haven't got the experience and don't let it get bigger first.
You haven't really done enough research to know how to grow or care for these plants, even though they are weeds you won't make it at this rate but it's your choice if you want to just screw around and do everything wrong.
I also don't see the connection with the title of this post, wanting faster growth, with the idea of making a bonsai. Bonsai and fast growth are mutually exclusive.
I can see you making it through flowering though if you let it finish, you're already in flower you say so probably don't have too long to go, 6 weeks maybe.
