well, you need to get some ventillation....plants NEED fresh air! Next, when you repot, I'd try some better soil....something with micorrhizae for better root growth. Also, you don't need to water everyday. I would wait a few days in between waterings. If the top 2" are dry to the touch, then add a little water, but your plant looks pretty droopy which could be linked to overwatering.

On the bright side, I do see some new growth and that is always a good side. Those yellow leaves at the bottom can just be trimmed off....good luck! :jointsmile:
