Zed  becomes  untargetable  for 0. 75  seconds and  dashes  behind the target enemy champion. Upon arrival, he marks them for death,   ghosts  for 3 seconds,

The mark is aplied after .75 seconds (so yes the mark appears when he appears) so you better wait for a while to qss, anyway as long as you cleanse it during those 3 seconds its the same but I usually recommend to wait for the last moment to cleanse it.
