yellow bordered leaves on phalaenopsis
 

My beautiful rescue orchid is having some issue! It has a yellow border around several leaves. It's been this way for months. Otherwise, she's healthy and happy!
No other orchids that I have are doing this.

It's probably fine. There are some that have a lovely light border around them and this may have some of the same breeding in it. Sogo Vivien is a good example of one with a beautiful variegated leaf.

I believe it's normal. At least your phal seems to be in good shape.:)
