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
