I have an Oncidium that I am concerned about. The older leaves are drying and become stiff like a palm and pull right out. But it is still getting new growth. Is this normal or is it in trouble? This is my first and only orchid of this type.

It was repotted from the original about a year ago. It is under grow lights and is watered about once a week.
Also if it is not in bad shape what is the trick to getting it to rebloom
Thanks
