About a year ago I got my first orchid and immediately became wildly smitten. I now have 24 in my window sill(s) collection! All have been healthy – even the tiny ones purchased at the hardware store have thrived and produced new roots and growth. The problem: This beautiful BLC Greenwich ‘Elmurst’ has developed small black spots on one of the leaves (first pic), and most disturbing, the newest small leaf is yellow (second pic). Also, two old psuedobulbs are shriveled. What is wrong with him? When I saw the spots, I immediately drenched with Physan 20. (He had very robust growth until the latest small yellow one.) I am ready to panic. All advice is appreciated!
