Can anyone give me a definitive answer on what these orange spots are on this plant?? I have done tons of research but am more confused now than when I started checking it out. I suspect either - rust fungus or a PH issue. It started on the oldest leaves and looks to be spreading up the leaf. It is only in the middle of the leaves and not near the tips. I checked for spider mites and cannot see any (or any other bugs). No nutes yet in soil and the the plant is 2 weeks old today. I had to mess with the hue in PS to make the spots more visible, otherwise plant looks good although there is some darker green at the tips of those leaves which are curling down ever so slightly. Thanks!
