I bought this Optimara variegated AV in May. I guess it had thrips. I thought I looked at it well in the store, but maybe I didn't. Anyway, when we got back to the condo, there was spilled pollen on one of the blooms. It could have been thrips, it could have been from being jostled on the ride back. Either way, into a ziplock bag she went. When we got home, I repotted it and right back into a ziplock bag and into my isolation area it went.
One leaf has a whitish powdery substance on it. None of the other leaves have it (any other white spots you see on leaves is a speck of perlite - I checked closely). Do any of you have any idea what this could be?
Here's a picture progression of this plant so you can see how it's growing. Maybe these will help determine what that is, and if it's anything I need to worry about.
This picture was taken May 30th.
