I keep learning from all of you folks as is the nature of this open forum thing... so let me pull all of this together for you.
First, I have recently learned to restrict your chopping of the plant to one time. You get much stronger and more potent buds if you stop with that first cut and however many primary kolas result is what you grow. It is OK to supercrop or LST after that... but the multiple topping method of pruning a plant into a bush shape results in one primary kola, and a bunch of 2nd rate bud underneath. If you want more buds, grow more plants. (this was the big lesson I learned so far in 2020)
So where do you chop? Chopping at different nodes has a different effect on how many primary nodes are created. Uncle Ben's method is popular because it results in 4 primary nodes! It also allows you to quad or mainline your plant very easily, producing very large producing plants. To use Uncle Ben's method you wait until the 5th node is rising up and could be nipped off if you wanted to. Instead, go all the down to between nodes 2 and 3... chop there, as high up as you can. Take the big stalk that you cut, and root it out, and grow it out.
If you don't play this waiting game but instead chop between nodes 3 and 4, a very interesting thing happens. It is almost like a FIM. It stunts the plant for several days trying to figure it out, but typically you get 3 main kolas, sometimes 4, and occasionally 5! It's like playing a slot machine... you just don't know what is going to happen.
If you chop between nodes 4 and 5, or anywhere up the stalk higher than this, the plant develops 2 main kolas and doubles your yield. Bend those down and do some LST on them, and you can get some great production this way too.
This, I think, is everything that I know about where to cut, as of this date.
