Yes, topping is worth it if you want to bush out, I did it in a different way, but this was a single topping, you can see what it looks like to start then how those 2 branches develop, this was topped at the 5th node then flattened once those 2 nodes grew out a bit, this is the same plant early after topping and first put into the net to what it looks like currently, you can see you see what those 2 new tops turn into under the net
If wanted each node can be topped this plant was just the main growth tip and then that’s it
Scrogger gave an excellent discription of fimming above, but I agree w it has frogged that looks like you did a topping (not a bad thing)
Here was 2 pics of one from the past at the end
