Deformed Phal blooms???

[Sandy4453]

This phal began blooming in mid February and the last bloom ended about a month ago. While the blooms were still pristine, the spike began growing and now I've got 5 more flowers (one yet still to open) but they're all mutations, one less severe but the other 4 look like this one (pics 3 & 4), a big departure from what they originally looked like. I've seen similar to this happen on second bloomings but never to this extreme. I'm so fascinated by it that I actually like my little martian blooms.

Any thoughts to share about what's going on with these? And yes, I use SuperThrive.

The first pic is from the first bloom, the next 2 are what's flowering, now.
