Milty Malady
....This morning I discovered this on a leaf of my miltoniopsis herr alexandre. The plant lives under a skylight near a mirror in a bathroom and has the longest bloom of any orchid I own (4 months!). It's getting a little less light now due to the direction of the sun shifting.
6 Months ago I'd seen something similar over a few leaves of an oncidium alliance plant that also started getting less light at the time (withered but subsequently survived by way of new growth). At the time I wasn't sure if it was calcium from fertilizing or a virus (but I assume calcium would be on all leaves).
Help.
