Hi. I had the same problem. However, I solved it with a bi-weekly watering of a small orchid fertilizer (literally 1/8 of a teaspoon). The water itself was taken from my patio pond. I placed the plant in a high humidity area near other plants. Let the plants drain out completely between waterings. The soil mix comprised real, finely chopped coconut bark, crushed egg shells, charcoal, phosphorus, lumus soil - basically nothing compact. Watch out for mealy bugs as they love these plants.
