I have two nobile types and am not an expert, but I don't change anything with them. I grow them inside under lights in coconut husk mixed with perlite and charcoal. The thermostat is set at 69 degrees. We have low humidity. My anosmum starts shedding leaves at the same time it sends up a baby, and shortly after starts budding. It's budding now with half the leaves gone, and the others yellowing.
