Need help, Not too sure what going on with the leaves I have this Neville haze growing. Recently I gave it calmag, and the leaves seems to not like it. Giving out light brown patches, looks almost like rust. Today the serrated tips of the leaves is turning brown. Any idea what seems to be the problem?

Spots on leaves Anyone know what's causing this? Slight discoloration and rust spots, mainly on older leaves. It's not that bad but quite spread out. did spray with neem oil recently, so is it just burn spots or a nutrient problem?
