hey there, you have root problems from chronic overwatering, you can tell from the puffy space between the veins of the leafs and the downwards pointing curls of the leafs. Good news is fixing this is easy ! basically water about a day later than you normally would to fix the overwatering issue. Then you need to break down the problem roots with a chelation agent. Cut out the rhiz and use the zym every watering. Hope this helps ! ๐
