She’s ready to top now from what I see. I’ve topped my autos in the past with good results, but then I tried FIM pinching instead and now prefer to FIM pinch instead. All you need to do is firmly pinch the new growth tip between your fingers, don’t remove anything. FIM pinching still promotes outward growth instead of upward, but stresses the plant less and you get to keep all of your existing growth instead of cutting some off. Good luck either way 👍
