All,
Over the past 2-3 years, I've had to re-learn how to grow my orchids indoors for either all or part of the year. The plants inside get RO water, so long story short, I've come to realize that many of my 'chids have been suffering from calcium deficiency. I've been adding Ca/Mg to my watering regime since I got to Texas, but it was not enough. In the past month or so, I've taken steps to increase my Ca dosage, but I won't see results until the end of the next growing season in many of my plants.
Its a VERY avoidable problem that masks itself as rot on new growths. Here is a link to pictures of Ca deficiency in orchids:

Here is a great written description of Ca deficiency in orchids, including how to fix the problem and why it happens:
