You waited way too long to top where you marked. When you top, it should be the top of the plant, not the middle.
If you are planning to clone what you cut off, then it's maybe useful, but otherwise you wasted a lot of time growing a big portion of plant for no reason.
Top as soon as you can when the plant gets to the node you want.
Right now I would top way higher (2 or 3 nodes up from where you marked) and let the lower branches come up.
Timing is key to keep your grow efficient.
