Is one getting more sun than the others? Could there be air pockets in the root zone? Could the bud have been damaged during transport?

I thought I got rid of all the air pockets, Not sure what you mean by the bud being changed during transport.

Check and make sure that :

You did not plant them past were they were originally grown
and don't water them so much i would think twice a week should be enough .

I planted them at the same level, I will cut back the watering to twice a week and see how that works.
