if any congestion is causing condensation (resting water) on your leaves, that might be a good spot to thin out, but the goal is to keep as many as possible. have a good reason to remove anything from the plant.
You could clear bottom part for better air movement, but no need to take anything away above balcony line.
Google : " weed lolipoping " and still, you need to clean bottom 30-40 cm max.
Have fun, huge harvest awaits !
Wow look at that monster, nice, I wouldn't remove anything outside myself. The sun arcs , leaves will have different ppfd at different times from different angles. No need, nature knows best. Let her do her thing.
