I've purchased Cuprex because this has both an antifungal and antibacterial option. I will follow it closely and perhaps I will cut off part of the leaf and then apply cinnamon.

Lemboglossum Leaf chlorosis

My Lemboglossum Violetta von Holm has bloomed last winter and new shoots are developing. But they have chlorotic spots. I'm thinking it might be a lack of nutrients or in worst case, something viral....
