Having a fair bit of leaf drop with my lemon tree but is blooming like crazy so it’s a bit confusing. The blooms lead me to believe it’s very happy but the leaf drop without much new leaf growth has me worried. Temporarily had to move so light level is less than in prior years but supplementing with grow light. Season is changing so could it be temperature related? Definitely not likely to be overwatering. I also wondered if maybe the significant blooming is taxing the nutrient supply. Anyone have any thoughts? I can send a photo later. Fallen leaves basically have a little bit of yellowing of the veins.
