I have 7 umbrella plants, 6 are cuttings from the mother plant. Unfortunately the mother's leaves aren't lush green and thick anymore and they have spots, some colorless and others are dark. The stems droop as well. I was hoping you guys had any insight on how to correct this. I have some Southern AG Fungicide I can apply if this seems like a fungal issue. The attached pics don't do it justice but it gives you an idea of what is going on. All the other plants are doing well and even began growing new spring leaves except this one.
