This is on my mind but haven't had a chance to investigate more closely. Up until the past few weeks, I observe plants at least 2x/day, sometimes more, so don't think there's been any mealybugs on plants, this has looked like this for well over a year, but isn't spreading contiguously, and IDK this kind of plant well, especially since its' ID is a mystery. Scale occurred to me... It was either raining, dark, or I was at work since I asked, will check it out tomorrow & post my discoveries here. TY for your concern!! :+)
