Is anyone familiar with this problem with their basil? It seems more prevalent amongst my lime & French basils than my others. It's always on the 'older' leaves, as opposed to the new growth. There don't appear to be any bugs on them & nothing else I would think of as a symptom. It reminds me of the thrips damage on my parsley & dill, except that there is no fecal matter. Both the top & bottomsides of the leaf are clean. These plants were started from seed and have always been grown indoors. They seem very healthy otherwise.
