Hello, I inherited a large 10 year old Night Queen 3 years ago and have grown plants from the cuttings however they have developed brown spots on the leaves and around the edges on some of the leaves. I have followed the advice on watering, light, soil etc. Also tried putting cinnamon on the affected leaves but to no avail. Should I be cutting off the affected leaves or just leave them alone? The plant is very healthy apart from the little brown spots.
