I think that it is probably lacking something but what is it?
Maybe too much light? I have all my orchids in the patio and block the direct sun with roses and other plants. I am new a growing orchids so I am not sure if the patio is a good place for them. I live in Southern California.
And just a tip....an orchid that is receiving the highest amount of light it can handle will have a reddish tint to it. Just be careful to not let it get past that point.
