I've had this Cym. for about a year now. It's planted in wood chip orchid mix and gets watered once or twice a week, depending on the heat. It's on the north-facing balcony in the early morning and moved onto the balcony again at 5 pm until early next morning. The plant has been doing well the past year (growing a new bulb and 2 flower spikes at the moment) but it has really big black splotched on the bulbs (old and new). The oldest bulb has dropped all leaves except one and the bulb in now brown and shriveled (which I know is normal).
What could these black marks be? They're both on the bulbs and some leaves (new and old). The bulbs are also quite yellow. Are they maybe getting too much sun? Not enough water?
