Normally I go for the third node and develop those horizontals into the cola carriers. Typically 4 colas on each branch but that’s not a hard and fast rule.
Sometimes the way the plant develops it is best served by changing the pattern slightly.
What I like about manifolding is I can easily isolate any branch for selective pollination or in the case of males, the shape really aids in pollen collection.
Manifolding adds a week or two to veg. and is a little ‘fiddly’ but a useful tool at times
