Hi there, I might be late to the party here but have a real problem with my monstera. It has been thriving since I got it in february and now in the last month has suddenly started developing these brown patches. I think it might be sun damage as it is in an east facing window (and we live in Portugal so it is hot at the moment - but has been like this since may). I have not noticed any bugs or pests etc and now have put paper on the window to stop the hot sunshine. I water once a week and once every two weeks with fertilizer. The brown spots have come on leaves that are new since I got her. It may have been over watered in July because I was away and my flatmate took "care" of it... but she assures me that she only watered once a week. Anyway really worried about her. Please help!!!
