Repotting new plants is asking for trouble because so much can go wrong. Plants don't like larger pots. They do best in the potting soil they are grown in by the nursery. Commercial potting mixes tend to be too heavy and retain moisture for too long. Pots without drain holes are a recipe for overwatering. Removing soil from the original rootball often does serious damage to the tiny roothairs. Inadvertent overwatering is much more likely after repotting.
For future reference, I suggest you keep your plants in their plastic nursery pots and set those inside something more attractive. If you leave the roots undisturbed you will have far fewer problems.
