Hello!! I recieved this plant from an online retailer about 3 weeks ago. When it arrived it had two yellowing leaves on it which I removed. Over the past few days I have noticed that one leaf has started to droop and turn slightly yellow. I have watered it twice since aquiring it, and I have allowed the water to drain fully, not allowing it to ever sit in any residual water. As you can see the plant has a new leaf coming out, and a smaller new leaf. I hope you can help me!! Thank you!!!!
