Mclellanara Okika not adjusting to new home

[joeytiii]

I'm a complete newbie with orchids having gotten two plants for Xmas. I then went out and picked up a Mclra. Okika at a local nursery here in Puerto Rico. The plant was under a black shade screen along with 1,000s of others. Because it was in full bloom, I kept it inside for about 10 days until the blooms dropped.

I understand this is a hybrid of Brassia and Oncidium and likes light so I moved it outdoors to acclimate it in the area I will be ultimately mounting it. It got about 2-3 hours of direct sunlight and I noticed the top of the pseudo bulb is browning up. I am only guessing that I have subjected it to too much direct sunlight at one time so I now have it on my porch where it gets no direct sunlight.

I am watering it only every 5 days or so by dunking and letting it drain. The porch gets a nice breeze during daytime.

What do I need to do to restore this plant to proper growing health?
