Your always going to have a bit of stress caused by transplanting, especially from one medium to another like that. Just cut down to 1/4 strength on your nutes and let those roots get comfortable in their new home.
Another to thing to consider when you think your plants are shocked is that the plant is just directing its energy to the root system for a couple days to a week. New pot, new home means roots need to stretch and settle in. It's not always a bad thing when growth up top slows down a bit after transplant.
Good luck with the switch over man!
