I desperately need help guys! I bought two Aurea clippings from a reputable seller in Thailand. Upon receiving them I noticed one had some rust spots. I started treating it with copper fungicide 2 weeks ago. It hasn’t done anything. It’s getting worse under the leaf. I’m aware with copper fungus you are to remove any infected leaves or stems but my question is how do I do so when it’s a single clipping ? I have both clippings quarantine! I’d appreciate any feedback at all. Thank you!
