Hi!
I'm relatively new to gardening.
I seem to have a similar problem as WKcai.
I already have an existing monstera deliciosa fir the past 3 months which seems to be growing very well so far. I usually keep it in my room by the window. In the photo, I was cleaning my room and just put it out for a while.
I was given a new smaller monstera deliciosa about 3 weeks ago. I noticed that the smaller one has those kind of brown powdery spots that can be easily wiped off. But they leave a yellow spot on the leaves where they have been. And the plant overall doesn't look as healthy.
The bigger one has some on one of the leaves as well.
I would wipe them off with a soft cloth dipped in light soapy water. But they will come back.
Are those some kind of insects or moulds or something?
I don't use any pesticipes. I haven't used any fertilizers yet on those 2 plants.
I have not repotted those 2 plants yet neither.
I was told I should repot the bigger one. I'm still hesitating.
The soil that it came with.
You need to click on the photo to open the image and see the details in the 2nd photo.
