Wendy is fine and not unhealthy at all, leaf "mutations" are common with cannabis plants and as long as she looks a healthy green colour and grows progressively, you have nothing to worry about.
Leaves with all sorts of numbers of blades - 10, 2, 4, 5, 7, 12, 9, 6, 11, 13 1, 2, 3, 7 and 8 are all possible.
