I will also throw in three more possibilities:

1) Insufficient food
2) Wrong fertilizer formula (too much nitrogen)
3) It is not seeing enough of a cool period to initiate spiking.

Many phals grow better if kept warm, but won't initiate an inflorescence
unless they see a week or so of 10°-15° cooler temps. Ordinarily, that
happens for in-home growers as Fall approaches, and the temperatures near
the window drop.

You made the comment that you " feed it with orchid food twice a month."
What's the formula of the fertilizer and how much to you mix up with water?

waving pruning shears over mine has worked....

but yes--how long have you had the plant? has it ever bloomed for you?
i've got a big white NOID that took a few yrs before it would bloom for
me--and it grows lots of leaves. but then, i have a golden peoker
daughter that's *always* in bloom--but also only ever had four leaves.
that's it, that's all it wants, and it steadfastly refuses to grow more.
