Phalaenopsis roots growing straight up, holes in leaves.

[Narttu]

Hi there
I'm very new to the forum and have a couple of questions about one of my phals. After killing two, (over watered the first and the second was in bark, which I just couldn't get the hang of) I now have two in moss that seem to be doing quite well.

Both are on a south facing windowsill, where I rotate them each day to keep the leaves growing evenly (I forgot a couple of days in a row and the newest leaf on the larger one is now growing sideways. Really hoping it will fix itself up!) They are planted in premium sphagnum moss, watered as they dry out, and fertilized with an orchid fertilizer with each watering. They both appear to be quite happy.

The larger of the two has 2 aerial roots that are growing straight up, I mean literally almost vertical. Is this normal? =\
There are also spots and holes in some of its leaves. I have looked for pests on the plant itself and in the moss it is planted in and can't find anything! Could somebody tell me what may be happening?

I have added photos below..

Thanks!
