Oh my goodness everyone, thank you for all the helpful replies!! I am glad to hear the Keiki is just a little buddy that can hang around and is most likely not hurting the original Phal

That is a new term for me, a "Phal", I love it!
To answer your original questions, DrDawn:
How are your orchid's roots?
-Well, to tell you the truth, I am not sure...none are on the surface and I do not know how to check when they are buried within the media...
It looks like you have it in a pot with lots of air holes, which is good, but the media looks very wet.
I had just watered the Phal when I took the picture, but in general, I feel like the medium may be not drying out as much as it should between watering. I water my orchids (all Phals) once a week, and this particular buddy (I call it "Keiki" for obvious reasons) would change from weighing anywhere between 8.7 oz to 12.1 oz heavier after watering.
When did you last repot it?
Good question! Before I started logging data about it, unfortunately! But judging from when I purchased the potting containers, I probably repotted sometime in July 2019 or August 2019, so almost year ago. That was the first time I repotted after purchasing the Phal from a grocery store. She has never grown a flower spike since repotting, but has grown the Keiki and new leaves. No new roots above the surface since.
What condition were the roots in? (Any chance you took any pics?)
I did not take a picture unfortunately, but I recall the root system was actually pretty ok looking in my novice eyes
All this being said, and this is kind of off topic from my original post...any advice on getting her to spike again? I think I had probably had her for perhaps a year in her original pot and medium before I reported her at the aforementioned time. I live in California in an apartment, and it's very hot outside now. I have a little shade, but I am still worried the 100 degree dry heat is just too much for her. I have been fertilizing every two weeks since March 23rd, I turn on a fan to cool her temperature at night since June 8th. But maybe she's just not ready in general? I also worry the fan isn't strong enough to drop the temp enough (it's a very tiny fan).
Also to tie it back to the original post after all, I was worried the Keiki would prevent her from flowering. But I would rather have the two of them together and no flowers ever than nothing! Attached some pics of Keiki as July 25th (before watering day, which is Mondays).
