Hi Ann Keh! Based on the picture, it looks like it is stretching towards the light. Could you tell me what direction the light is coming from and how far it is away from the window? That might help me diagnose your problem. The soil looks a little heavy, and the pot looks a bit big. This causes excess water that the plant cannot use to remain in the pot which can cause root rot. I would re-pot your plant into a pot that is one or two sizes smaller (make sure it has a hole in the bottom to let the water drain), using houseplant or African violet potting soil mixed with 50% perlite. I use this mix because it is cheap, easy to find, and my plants do great in it, but I have read that a lot of people have had great success with a potting mix for tropical plants created by tapla (Al), another user on this site. I think it is called 5:1:1 mix or something similar. The soil looks a little too soggy as well. Make sure to water when the top inch of soil feels dry, the soil should feel moist but not soggy. I hope this helps!

Have a wonderful weekend,
