Don\'t know what\'s wrong with my Calathea.
It\'s been half a year since I got it and everything was perfect till one month ago or so...

...I usually water misted it almost everyday, and watered it when I thought it was time to do it. Now, I stopped water misting it \'cause I\'m afraid that too much water can be the problem, but It\'s rapidly getting worst :-(

What should I do?... Is it some kind of fungus?... Will the affected leaves ever recover?...

Can anyone help me?
