Not sure what you're saying abut lemon speckling? Can you share a picture? Mines got (is that gramatically correct) some brighter yellow and orange speckling in his yellow areas as well as patches on his back and sides, but I'm not sure if that's what you're talking about. My digital probably won't pick it up anyway, time to invest in something a bit more professional! LOL.
