What’s an optimum LED height with an uneven canopy?

Ooo, kind of a tough one. You'd want to keep your lights at the perfect height above the highest top. I did notice the right plant is kind of shorter than the left one so what you could do is maybe stack some things under the right pot to keep both plants even. As for the colas being uneven, that should have been dealt with during vegetation and it gets hard to deal with during flowering because the stems harden up. They will still provide you with descent buds but you can take this all as a learning experience. PS: I have the same lights and the same tent 😝
