Yes you can send it to flower now but I would take those side branches and gently pull them out and tie them so you get better light penetration to the lower budsites. This will improve your yield an bud quality. Good luck in flower!
@WeedManHD hi mate if you aren't on any schedule may I suggest you do some basic LST to them for another week or two Then flip to 12/12
I believe the extra effort and time could turn a small yield to a fairly decent one IMO Best of luck
Some people start from 12/12.
Id say you'll be ok, just won't be a huge harvest.
If I were you, I'd train it, top it, defoliate it and in 2 weeks make the switch.
