Spoke too soon about bella. Help!!

[Blondie]

Screeeeeeeeeeech!

That is the sound of my happy record halting because after bragging about how great my orchids were doing in my last post (I knew better than to be positive ), I realized my little bella seems to have a brown petal.

It was there when it hadn't opened yet, but I thought it was part of the orchid's coloring. Now I'm not so sure.

As she opens, I'm noticing that one petal is a lot bigger than the other one and the smaller petal is brown on the end. Is this "coloring" of the petal or am I hurting it somehow.
