Q.Lemon tree
So the leaves have been yellowing and I don’t know why. Previously I was overwatering but not anymore, however they are still yellowing. Any help?

They are suffering from a lack of light! These require more light than is available in most homes. Unless you have a south facing window, where they get sunlight all day unobstructed, then they won't do well without supplemental light.
Generally, 100 watts per tree will keep it alive, and 200 will allow it to fruit, as long as it is maintained for size. Otherwise, they will lose their leaves in the winter, even indoors. This is a semi dormant state to protect itself from less than ideal growing conditions.
