These are my first lotus plants and I dont know much about them. I have grown them from seeds. Roots are in a container filled with soil,organic compost and gravel. This pot is inside a big container filled with water. Also its a rainy season here with temp ranging between 25 degree celsius to 30 degree celsius.
From couple of days leaves started to rot. Is this normal behaviour for lotus? Or i am doing something wrong ? How frequently i should change water in the container? I last changed it around 4-5 days back.
