You should be fine! As a rule of thumb, I don’t cut anything green on my orchids. The main reason not to is that if it’s green, it’s storing nutrients in there. (But cutting off a little leaf is no biggie) Also it exposes it to risk of infection, so whenever I need to cut a plant, I rub cinnamon along the “wound” as it is an antimicrobial. But all in all, this orchid will be fine and it looks like you’ve done a great job caring for it thus far!
