Whoa
I'm back with this one, I had decided to terminate her but then I thought kind of "what the hell, I'll be giving her her time, I have no rush, I've just started autumm-winter crops and I can keep this bitchy dwarf where I keep my autoflowerings". All of a sudden after nine weeks from seed, she looks like thriving and willing to complete her life cycle. I'm glad to have give her a chance. But I did not because I had been merciful with her but that I didn't lose much keeping her as long as she was not the only plant I had.
Regarding training, I don't know if it is advisable that I stressed her, but I can't afford to let her grow much (if she ever does that) and I'll have to top her /mainline/ etc. her to slow down her growth, while waiting for an opportunity to put her to flowering in the photoperiod grow room, which is by this time, already full.
