To me it looks like phosphorus deficiency. Most likely due to pH too high.

This looks like something I had before when I overwatered some of the leaf tips started dieing like that. Best to have a bit of a dry cycle in the medium so its not so waterlogged. then anaerobic bacteria flourish and upset the dynamic sometimes cause rot or PH swings. Good Luck!
