Hmm, I will have to research some of those causes. I too have leaves that are turning brown but I haven't really thought about what might be causing them. I generally just trim off the brown every few days. I do know that I have some spider webs that are attaching to my leaves and around the base of my plants. I haven't actually seen the spiders, but the webs are there. Other than scorch, streak, and aphids, what other types of issues should I look for?
