Any idea what this is? Many leaves are dying on the plant, wondering if there is a way to save it. I have forgotten the name of the plant, but will update when I find it.
Ctenanthe lubbersiana? That patch with the darker spots looks fungal to me. I would check the roots, if they look healthy not dried up or rotten, I would get a fungicidal spay like captain jacks. Applied at night to avoid burning leaves. Could be an airflow issue as these plants like to be evenly moist and in relatively higher humidity or they crisp up along the edges. Without some good airflow fungus can spread.
Thanks, I'll take a look! I did check the roots recently and couldn't see any rot. It's always been in good jungle soil with airflow and drainage so I have been at a loss for what it needs.
