I have recently (about three weeks ago) gotten a palm sago indoor house plant. About a week ago I started noticing some severe curling in leaves and they seem to be dying I heavily watered it when I first got the plant, and about a week later emptied out the excess water that drained. I have been warned of over watering and since then haven't added any as the soil is remaining moist...I'm not sure what the problem is? Too much/too little sun? Or too much/too little water? I have never owned one of these before so any help is appreciated! The last /brightest picture is when I first got plant and the rest are recent. This window receives partial sunlight for a few hours a day.
