Thank you for responding, first of all. This is new for me. In fact, it seems to have occurred just after Enchanted by Nature was released. I tend to get my harvestables to the Perfect level, to help out the families who sell them. I am at a complete loss. If it isn't harmful, I'll just ignore it.
I think it's because they've just added the label tracking fertilizer level. It doesn't hurt the plants to be unfertilized, it's just letting you know when you can or can't fertilize - though if it always shows depleted after they reach perfect, I would agree that it would probably be better for the label to be removed at that point, just to reduce confusion.
