Red Tip on Spike? Please HELP!

[Newbie3]

I'd be surprised if it was getting sun burnt (I'm not saying it is not possible) but no where in by house gets ditect sunlight so even with the Phal sitting right on the window sill it may be in a bright-ish area but its not even close to direct light. Ín my house, you can tell that the suns up beacuse it gets bright, but you could never say which way the light was coming from... its very dreary sometimes.

As far as the roots, from what I can see they look plump and green with a foggy coating on them in certain places that has always been there. I have not removed it from the pot to further inspec the roots, should I? Will it be detrinmental to the plant to pull it up and investigate?

Ok I think I figured out the pics, Thank you!!! one is kind of blurry but you can see the discoloration.
