spike or root on phal equestris var alba

[playtime8978]

can somebody with more of an idea tell me what I have on my new phal equestrtis var alba, I thought at first it was shooting out an aerial root but then the shape of the end of the growth looked a little like a flower spike forming, It is the first time I have seen a growth on a Phal my other ones were all in bud or flower when I purchased them either way I am happy as it means its growing if it a root or if its a spike I have the chance of blooms thank you for your help in advance.

PS I appologise for my photographs my camera skills are somewhat lacking
