Hi Kachow
Welcome to OB.
It looks like a Phalaenopsis orchid.
Unfortunately all your previous replies grouped themselves into 1 post so you still need to do a few more posts until you can upload a picture directly on here.
We definitely need more info to be able to help you, as well as a pic of the area causing you concern.
Common Qs are:
What is the Phal potted in? ie What medium? Bark or moss or...
How do you water it and how often? How do you judge when you need to water?
What are the temperatures like, day and night, in the grow area?
Has it been repotted since you acquired it?
Have you had a look at the Thread titled 'The Phal abuse ends here'?
