I’m a bit shy to quote maffs again, having been told.
The way I do it (now this is just me) I count pairs of branches above the cotys. I count four pairs. I cut the apical meristem (main growth bit) above the 4th branch node.
I then try to keep the top pair flat(ish) until the next pair catches up.
The next pair down (for me) are cut for clones. The lowest pair down usually get stripped for being too weak to be of much use. Unless they aren’t.
Edit: the node spacing is wider than yours so easier to see. The cotyledon node is withered now and just out of frame.
So this one I only counted three up from the cotys because the first line looked useful enough. The lowest pair will come off for clones when they are each 3 or 4 nodes out, or 4” long.
