Youre Phal looks healthy and happy, and the new leaf seems to grow just the way its supposed to

The redish color on the new leaf is pretty common, and ive seen this on several of mine as well.
Its often a hint on what color the flowers are, but this is not the case here. Sometimes the leafs will have a vaint redish color underneath if the color of the flowers are brigth redish/purple as well.
As for the growth on the spike, its a bit early to tell what it is for sure... I think you will have to wait another wekk or so, to be sure.
