I have had my 1st orchid around a month and a half now. It is a Phalaenopsis Orchid. I grow it outside. It recieves morning and evening sun. I've notice in the past 2 or 3 days, what looks like gold or silver spots on my flowers. I do not know if this is normal when flowers are getting old, or if I might have some kind of problem. Has any one else experienced this?
