percy, your description of light hazy white spots... then the pics of the necrotic scarred patches... I'm thinking thrips... look for their tiny blond larvae on the leaf surfaces... they look like a splinter... they leave pale, almost shiny silvery chew trails on the upper surfaces of the leaves, working from the bottom of the plnat up.
But you have something else going on there too I think. hmmm....
Why don't you start a new thread with these pics, since it is a differnt prob?
