I have this Meyer lemon tree in a pot. The leaves are slowly but steadily falling off, and each little lemon turns completely black and falls off before it even grows to like a centimeter or two. What could I be doing wrong? I have a soil moisture meter and I only water it when the meter reads “dry”. Could it be my grow light isn’t right or isnt strong enough?
I had this problem with my citrus tree and it improved when I moved it to direct sunlight. Yours doesn’t look nitrogen deficient so I would suggest a stronger light/move to sunlight
