Hello all, This is a C. lueddemaniana that was a recent import this Spring. It has established nicely, as the tallest p-bulb is the most recent. Today, however, I noticed that one of the older growths had a severely yellowed leaf (the underside is identical). I just took the shadecloth down last weekend, so I thought maybe it unluckily just got blasted by too much sun. Still, it is a C. lueddemaniana (supposed to get lots of sun) and I haven't noticed anything similar on my other plants, some of which were adjacent to this one. I'm guessing this leaf will just die for some reason and fall off, but I'm thinking this isn't a pathogen or nutrition issue that threatens the plant. Any experts care to weigh in? Thanks, in advance.
