lol, random i know, just noticed some discoloration on lower leafs, just wondering if anyone growing outdoors has seen this and know what it is, i don't see any bugs,
I'm not exactely sure what that is but, I would hit it with some insecticide for sure!
If I had to put money on it I would bet that its some sort of microscopic insect of some sort. I've heard that you can use a mix of 1-2 tablespoons dish soap in a gallon of water, the theory is that it will suffocate what ever it is.
I would get something a little stronger that will actually kill it, and make sure to spray the under sides of the leaves aswell!
Looks like spider mites. Check underneath the leaves and near the stems for little orange or off white spiders. Also, look for webbing or little white eggs along the middle of each leaf.
