1.) How did you take your cuttings?
2.) Did you root them first?
3.) How old are they?
4.) My best guess is you have a pH imbalance. Fix that, and you should be good. Soil pH needs to be anywhere from 6.3 - 6.8
5.) dillhole is correct in saying that clones need to be slowly acclimated to life outdoors.
