I would try and water less, mist more. the roots are a little shocked I am sure. I have gotten away from watering when I transfer plants, there are so many variables.. root structure, soil components, soil moisture content, nutrients, temps humidity.. etc.
I started misting my new transplants and have had good results. as long as your air is moving and humidity is under control mist away. Using soil that is well prepared and has similar moisture content to the plug I wait a few days letting the roots adjust I start watering, adding to the schedule as the plant needs it. I saw two of my buddies grows fail this summer due to over watering.
