It actually makes a lot of sense when you consider that every strain and even different phenotypes of the same strain has its own unique light saturation point. Some genetics are light hungry beasts, while others are much more sensitive to high intensity. You’ve basically discovered that this specific plant is the "diva" of the group! Since the other two are thriving, you don't want to change the environment too much for them, so raising the light or even moving the sensitive plant to a corner where the light spread is naturally a bit weaker can help. Monitoring is definitely the right move, just give it a few days to show you if it likes the new height. Happy Growing Growmie🌱

That light setup is absolute overkill. They are all more or less stressed sadly.
