Seeing that I'm in Miami Beach, I'd have to go with insects.

I would suspect that relates to insufficient humidity or insects of some
sort. With rare exception, every spike that form on mine bloom fully.

I often see spikes forming and then drying up.
The Vandas are watered every morning, unless
it rained at night. I still get several blooms. In fact
several are in bloom right now.
Are we over watering or is
this just a natural occurance?
