Can anyone give me an idea of what is going on here? I have several varieties of peppers I've started indoors this year. This issue has only come up on some, but not all, of some jalapenos that i saved seed from last year. This just popped up all of a sudden. I've looked and I don't see any visible pests. Looking with a handheld microscope i can't tell much. Any ideas would be appreciated. Should I quarantine them?
