Thanks Trapper, I had a freak out moment tonight when I wentwent to check on how they're liking CFL free day and found a tiny flying insect dark in color with a blueish/greenish tinted wing color as though they were covered in an oil spill. I killed it after chasing it a bit, and didn't find any signs of anything on any undersides of leaves, or any other insects, but still not happy to find any insects. I'll have to do some research and see if I can find anything out. At least it wasn't an aphid.
