Please help! I've been googling solutions for weeks and can't find anything that looks exactly right. I bought a healthy and happy zns. Murasakikomachi from an orchids greenhouse in December. When I brought it home I made the mistake of putting it in front of a heater with no light and it started to turn black so I moved it to a spot with lots of light and a humidifier, and started watering it a bit more. Months later and I've lost almost all of the leaves...they get black speckled on the underside of the leaf, which spread to the top as the leaf turns yellow (I did the tissue paper test, not bugs). The base of the leaf (the beige part covering the bulb) is becoming speckled, and I just found that one of the bulbs was black. I'd be extremely appreciative of any help!!!
