Could be a good call camille. If you have an acidity test kit ...... could maybe try that. Otherwise, a repot could certainly help.

If more than just a couple of tips are changing colour, then definitely ----- can respond. Time is on your side, as you're watching the orchid like a hawk obviously, which is great.
