New phaleonopsis hybrid orchid with yellow spots on leaves

[PeggyO]

Hi everyone ,

I am hoping for some advice, I became the proud owner of a phal orchid in early October. Soon after receiving the gift I started researching care tips and came across this site.

Since then I have stopped over watering by letting the rots become silvery green in color and re-potted into a better drainage plastic pot. I also started spraying the aerial roots once daily. While re-potting I cut three roots off that were brown and my orchid let me know it was very happy by growing two new leaves and more roots.

I thought I would try rePotme's feed me plant food for the first time at the end of last week and when I came home today I noticed two quarter sized yellow spots on the bottom two leaves.

I did not see anything on the forum where the only visual problem was yellowing leaves, am I still over watering? I know on other plants yellow leaves usually mean over-watering. Could it be the fertilizer? Or something different all together?
