what kind of disease is this. Can someone help me to identify this:
I'm sorry you haven't had a response. I was curious too. I can't tell from your photos what the problem is. Is it the streaky leaves or the spots? Is it possible a N deficiency? Can you post more photos? I notice you have a lot of CHC in the picture.
What makes you think its a disease?
Any pests on the underside of the leaves?
