Hi all, I bought a Monstera from IKEA around 20 days ago. The first picture is when it was bought. The diameter of the pot is 20cm. I put it in between of two south-faced windows, with a thin layer curtain. After several days, some of the leaves started to develop brown/blackish pot on the edges. I was afraid that it got too much sun so I moved it to the other side of the living room, which is around 4 metre from the window. Today I noticed that one leave starts to turn yellow. I guessed that it might because it gets too little sun so now I moved it back to the spot in front the window before, with the curtain in between to make the direct sunlight into indirect sunlight. I am living in Stockholm, Sweden. I have watered the plant twice since I got it, every 13 days. I watered it until the water drained through the bottom. The plant is in a plastic inner-pot with drain holes and an outer pot with no-draining holes. I put some rocks/stones under the inner-pot to lift it up so there is some room between the pots for the water to drain through. Please tell me what I am doing wrong with this Monstera thank you!
