Oncidium not flowering, what am I doing wrong?

[Awsorchids]

Hello all,
I'm new, and semi-new with orchids. I've got an oncidium that was flowering when I bought it (about a year and a half ago) dark red and yellow, but hasn't flowered since.

I had it inside on my kitchen table receiving southern light, but I learned that it wasn't getting enough light, so I moved it outside about a month ago (next to very happy cymbidiums).

Now its on my patio receiving southern light from sunrise to about noon. Now, it's leaves have gone from dark, dark green to moderately light green (good, right?).

I water it about every 5-6 days and feed it with orchid bloom booster 3-6-9. My temps are night 50-55 and day 65-75.

Why am I not getting any blooms? What am I doing wrong?

Any advice or tips would be very much appreciated!
