Interesting. I don't use it all the time, just occasionally, no more than once a month probably. But I know I had used it on this at the time the spikes were forming.

I've not had any other orchids react to it, but it was the only thing I could think of on this because it's the only thing that was different from previous years. (I've used Shropshire Seaweed on the plant in previous years, but not when it was spiking). I've also heard of other rooting hormones potentially causing such things, which is another reason I thought of it.

As I said, mine went back to normal flowers further down the spikes, and mine has flowered fine before, so I wouldn't worry about it.
