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?
hm, the leaves are a bit dusty, I will definitely try cleaning them. As for temp, I am in the northeast so not too much I can do about it (temps are around 18c/65f). I just re-potted it into a larger pot than the one I bought it in, and added some fertilizer when I did that - I’m wondering if the other commenter is right and maybe its too much fertilizer
