Heaven Scent Ondo Leaf Problem
By now I's sure most of you are thinking that I shouldn't be even standing NEAR an orchid, but I have yet another problem. This has just happened since I moved plants to our new greenhouse on November 1. We had an unseasonably warm spell, followed by an unusually cold spell with temps at about 40 at night. This Oncidium hybrid is very close to the east side of the greenhouse, but I wouldn't think this is sunburn since I have most of the sun completely blocked by our house (yes, not ideal, but it was the only spot we had) and the overhead light is softened by two layers of shade cloth. Is this cold damage? I wiped the leaves with alcohol...nothing came off. Why are the leaves a mottled turquoise/silver?
