Some time ago Roberta pointed out to me that many of these zygo hybrids have lots of different parentage. And from what she said it appears to me that the parentage greatly contributes to how vigorous the plant is. I have some that just grow like crazy, like weeds. And then I have two that do this, they grow a bulb and lose a bulb. Yes, before the leaves fall they do get spots on them and those spots are not bad. I just tossed a zygo that had completely black leaves. If you're concerned about it spray it at regular intervals with neem oil. That's a fungicide as well as an insecticide and all natural. Unless you grow this particular plant, I think you would expect different things from it. I don't see that you're doing anything wrong, from my experience it's the nature of that particular plant. ES tells me that they like to grow on the cool side, you might try reducing the temperature.
