Why is this orchid spike behaving this way?

[Brutal_Dreamer]

As Amey noted, sometimes temperature can cause this to happen. (Both speed up and slow down spike development)

Thank you for your answers. I know temperature can speed up or slow down spike growing, but all of my phals are in the same room, with about 70-74 degrees constant temperature. The other spikes are growing very well. Here are 2 pictures of spikes from my other phals, spikes which are the same age as the one in the previous post.
