That's big enough to top UB style for 2 or 4 colas. You've got 4 nodes. I would feed it and wait a little bit. The tops are going to get way taller than that and that plant needs to be fed. Get her healthy first.
I would let her grow to about 6-7 nodes so she can develop some good roots. Then top above the second node (don't count round cotyledons). Check my last post and you can see pics of how I did it and seven days later after the top of five different strains. http://www.rollitup.org/newbie-central/654674-im-ready-blue-og-white.html
The way that plant looks, if you start choppin on her you'll kill her bro. You need to feed her a little, and get her healthy enough to start working on her. If you cut her up and she doesn't have enough root system to support the loss of foliage she's a gonner or will grow so slow she might as well just die. You can always grow her out a little and chop to a lower node later after she's healthier. It would take about the same time as cutting her now and having the slow growth forever. Just some thoughts. Peace out.
Before u go chopping away u need to get her healthy first and get some solid lighting man if u top that thing now the chanecs are it'll prob die
yes she needs to can some strength and grow some more nodes before you think about topping her, also what size pot is she in now? Topping can be done twice for a total for 4 colas if done correctly, im sure you know this because you are not asking HOW to top but IF you can, once again for sure wait, but as long as she is Vegging you can top her, Just NEVER top a flowering plant (hope any of this helped) Good luck buddy!!
Ya, I'm gona call bullshit on ppl tellin you not to top...here's my very first cross breed bean , it wasn't doing to good UNTIL I topped it... now she's taking off and doing good going into her 3rd week...usually they're bigger by now...oh well it was my first attempt at pollination
