Depends on how you plan on growing her out and/or how many more potential bud sites you want. Personally, I would've topped her after the 4th node, started her on some LST and let her do what she does best, but that's just my personal preference. She looks like she's quite bushy to me and ready to flower if you want. However, if you want more bud sites, then I'd top her now. I don't know how flexible the main stalk is, so I can't truly suggest any serious LST. You can try, but be very careful.
