When you get your clones from the clone guy, have they been hardened off atall or do they come straight out of the humidity dome?

If they do, you will be subjecting them to major shock which will either kill them or stunt them massivley. Builld or buy yourself a Humidity dome. Then, ease them into their new environment over the course of a week. Up until they come out of the dome, they are taking a lot of water in through their leaves and the roots are growing under the soil. You are asking your plant to switch the way it takes water up in an instant and the plant can't do that.

Even better for you would be to insist that the clones are hardened off before you purchase them.. 1 less worry for you
