I have two Monsteras under grow lights since I live in an apartment. I’m usually not comfortable leaving the curtains open nor is the window area safe. It seems that the window is pretty old so cold air seeps in too much. It also gets too cold. I have them in the corner of the kitchen. When it gets too cold, I also have the heater on. It didn’t look like that before, I can’t remember when. I wanna say it’s the soil but also the heater? Or the frequent temperature change. It did so good during the summer. I want to know my next steps. Do I need to repot or separate them? They seem to be pushing apart their nursery pots too.
