Phalaenopsis leaves with discolored, yellow and brow spots
Hi guys!
I'm from Italy and I'm a young girl that love orchid species. Since few months I've problems with most of my Phalaenopsis. I'm desperate, every time I discover a new orchid sick! New yellow and discolored spots, and brown spots on the leaves.. What's happening? What kind of pest is that? A couple of months ago I made a treatment for prevention red mites.
Thank you for your help
