you just dont want tall that blank space between nodes, it makes for tall skinny plants that will usualy not be able to suport bud wieght, but hey put a fan on it and strengthen up that meristem! the branches are the real thing you gata watch for now. those are were the buds come in. closer nodal growth means less, bigger buds because the buds bundle together. if the plant is streatched like that itll mean more, smaller budds.
