I just purchased a meyer lemon tree a few weeks ago from a local nursery. It already had two green lemons a little smaller then a baseball. It also had some buds. I replanted in a bigger planter because the one they had it in was too small. Everything seemed fine it got two new little green lemons and a whole bunch of buds. A few days ago the buds started opening with great smelling flowers. Then lately the bottom leaves are falling off. They are turning a lighter green not completely yellow but not as green as they were. More and more are falling off every day. It still has buds opening but some of the first opened buds are starting to wilt away. I am just wondering if anyone has ideas what could be wrong and how I can fix it. I also noticed that it has a slight lean to one side. I turn it in the light so it gets sunn every where. It stays in my kitchen window that gets sun all day long. If anyone can help I would greatly appreciate it. Thank you
