Did I repot my phal correctly?

I re potted my phal several days ago & was wondering if I did it correctly. I wasn't sure how much potting medium to use. I repotted because I wanted to take it out of the plastic container it originally came in. It looked very cramped. This orchid was purchased at Ikea. I used Miracle Grow Orchid Potting Mix. Also, about 2 weeks ago I had to cut brown patches off the leaves due to what I believe to be sun exposure. I wasn't sure if repotting so soon after doing this would cause too much stress to the plant. It seems pretty healthy otherwise.
