More importantly you have a nutrient lockout going on. Check your ph level safe at 6.5 for soil or 5.8 for coco/hydro. Give her a flush and lay off the nutesfor 5 or 6 days. And you can top at the 3rd node when she's healthy, don't try and do it until she start to recover! 👍🌱
Couldn't agree more to Fruitgrowers answer,
your Damsel isn't 100% healthy. Before you cut anything off your plant, make sure she can take it...
Good luck.
