Help! Whats wrong with my Monstera? I’ve had my Monstera for about 6 months now and noticed these cankers or something like that growing on the underside on some of the leaves. I water the plant once a week. It positioned next to a window but gets a good amount of shade and sun throughout the day. My apartment is air conditioned and humidity is relatively low. Any advice?
