So I came back to NYC from San Francisco late last night.
I spent about one hour watering all the plants. I was gone for only four days, but all the pots were quiet seriously dry. They are all alright though.
Anyway, Golden Girl's spotted leaves got much worse, so I trimmed off two leaves.
At the time of purchase, I had the store guy trim off one leaf with ugly dark spots.
Now total of three leaves gone.
I believe it's fungus. It spreads quite fast and the spots were getting pretty large (one was nearly one inch in length). nearly black center with brown area growing larger in a circular manner surrounded by a slight halo edge.
Side note...my twinkles are shooting up new growths, but the older leaves are getting plagued with what I believe as fungus. They only had some very small spots last year, but this time, I wonder if the fungus spores from other oncidium hybrids found their way on those little leaves. hmmmm
Whiney Houston's passing is quite depressing and I feel the urge to go out and buy millions of brightly colored orchids to cheer me up.
