At one point in time during winter I had black tips on vandas roots. It happened rapidly on those that were standing on the windowsill. I decided - it happened because of too cold environment near the glass when it is -25 outside.
I moved them away from the window and they resumed growing tips again pretty soon (in a couple weeks).

Hm, that could be a cause. I have them near the window since that's where they get the brightest light.
