Default oncidium with black spots and yellowing leaf tips.
Hi. I have a new development with my orchid that had develop black spots. Now it appears that there are small brown spots with a light border, as well as yellowing leaves(starting at tip). This plant has just gone thru 2 bloom spikes and 2 more are developing. It has begun to develop new growth. I don't have it near a humidity source, because I have it in isolation. HELP! what is going on? Is it part of die back? Thanks for any advise Mo Boggie

Without a picture, it is difficult to tell. However, here are some great sites that will hopefully be of some help to you...if I have typed them in correctly:

Are the yellowing leaves bract foliage (on the sides of the pbulbs)? Or growing on the top of the pbulbs?
