I have an oreo x leuco that has been having diffuclty this year... There is white specks as if the green pigment has been removed also there are some browning sections of the leaf. I've checked it thouroghly for pest and have even spayed it with ortho but it still seems to struggle. I have one other sarra (psitt x leuco) slowly begining to show the same signs. Also one "Judith Hindle" that only sends up wide leaves with very small pitchers.
