    These marks have been on the plant since i started it indoors at the beginning of April. As the plant grows (and is now outside in a shaded spot), they seem to spread. I don't see any "activity", ie moving bug parts, but they appear even on the new growth. Is it a virus? A pest? An abberation in the plant?
