I have this one, and boy, it is a strong plant! I found it at the grocery store! all their phals looked awful, having been dried out for weeks if not months....this was the only one tagged, but I bought them all for $2 each!
anyway, they all perked up and I gave most away as gifts...this is such a majestic white, I had to keep her....
most of them were dead on the bottom of those horrible pots, so I took them all out, just whacked the bottoms off and put them in 5" net pots with a bit of large bark and charcoal....man, did they go crazy!! within 2 weeks they were all re-hydrated and saying THANK YOU!
sometimes, you repot even if its the wrong time....but, back to your orchid....I don't think phals are as particular as some, so I think you would be fine to repot now...if the ariel roots can be tucked in, do so....some plants just like to make ariel roots, others are escaping the pot because they don't like whats in there.....
some phals get too long stemmed over time...what I do then can appear brutal...but, I whack the stem down to pottable size....usually those bottom roots are not doing much good....and the ariel roots get buried.....
phals need BIG CHUNKY media....so air can get down in there and drain rapidly when you water...
good luck, and here is my sogo....just sending another fat spike!
