I think they should be fine. Sometimes my plants arrive like that because it usually takes an extra day or two for Priority Mail to get to me (and they're going to remove our Bakersfield Post Office Distribution Center this summer so everything will have to come out of Valencia down by L.A. after that!). I just remove the yellow leaves that look whitish all the way down and then clip back the yellow on the others, and amazingly enough as soon as those plants hit the great outdoors they start greening up! I've had plants that arrive looking really awful, and one week later you'd never know it.
