Brown discolouration after pruning

[NYCorchidman]

Yep, normal thing.

Some phals terminate their spike by browning from the very tip as soon as the flowers all drop while some remain green spikes for months, which may or may not rebloom.

When the spent spikes stay green for a while, I usually trim the spent spike on the node where the first flower was attached just so I don't run into the annoying tips pointing everywhere. lol

Then some plants rebloom and some don't.
Only time will tell.

I have one phal hybrid that is spiking off the spent spike for the second time. can you believe it?
It is also making a brand new spike in two years! yay!!!
