My china doll was doing great. I had it placed near the south window until my son, aged 1, started to climb on the sofa near the plant. I moved it into the kitchen which is an eastern room, but not much light due to the house next door. The leaves have started to turn black and fall off. Even the new growth is turning black on the edges. Am I watering to much? Before it was in need of water alot as it was always dry, I kept on watering the same schedule and think this is the trouble. I have placed it today in an east window which will get a lot more light, and am hoping this will help. Any ideas?

one thing to remember. when you fertilize a house plant, you only want to do it at half strength.

from what i am reading, when you moved the plant, you didn't alter the watering to match the new conditions. let the soil dry a little more before you water it. that should help.
