My dracaena marginata has not been doing well of late and I figured it was because the pot it was in was too large, so I repotted today and I found a cluster of little teeny tiny white elongated things underneath some of the leaves. They are all in this one area and are clustered together. They are individually very small, less than half the head of a pin. I attached some pictures but my camera's not very good so it's pretty blurry, but you can kind of get the idea. Anyone have any ideas as to what the problem could be? I tried doing some research but the only little white bugs I read about were mealybugs which I don't think this is. They don't move at all and they seem to be smaller than a mealybug which makes me think it might be some type of eggs.
