Terminal spike?

[Biscuit&Gravy]

Hi!
So this January I was walking by a grocery store phal. and it looked so pathetic that I took it home. Since then it made two new leaves (and working on a third) and made a TON of roots which are working on growing out of the slits on the pot. However, it pushed this spike out a couple weeks ago in a weird place. I've had phals for a year so I'm a bit newish to them. I was just wondering how I should care for this plant with it's odd placed spike.

Thank you!!
