Well, Vorräten has already said everything that could be said, but my personal opinion to answer your question precisely is that the side branches could lose a few sun leaves pointing inward, but don't overdo it. As already mentioned, this can also reduce the yield because these leaves are energy converters and storage at the same time, which should supply everything above them. Therefore, it should be proportionate. That's how I learned it. Good luck and good job! Very nice work, it's fun to watch.
