Black/brown spots on monstera leaves? What the title says. My monstera keeps getting these dark brown-black spots on the leaves. Another leaf is affected every few weeks or so. I've tried (gentle) bug sprays, moving her out of direct sunlight, trimming the affected leaves, but nothing. Right now she gets indirect sunlight through a NW-facing window. I water whenever the soil feels dry (in this summery weather that's about once a week); usually I take out the inside pot and water over the sink to let the excess drain out, then replace the inside pot in the outside pot. I keep dust off her leaves and try to make sure she doesn't have wet feet (leading to root rot). I'm really not sure what else I can do; nearly all my other plants are thriving under the same conditions. Any help is much appreciated!
