Hey brother, never done this before but since no one else responded...

Would venture to suggest they are stressed pretty severely by the move. The move from indoor controlled enviro to outside is extreme, usually. The change in temps, light intensity, humidity, wind, roots disturbed, etc. As such, they have shut down transpiration and/or can't keep up w the demands. This is my best guess.

Assuming the soil/watering/feed rate/pH is solid, and the temps aren't xtreme, they will rebound over the coarse of the week. I really don't think they will be fully "normal" & you will have issues perhaps with finish times, but should improve greatly from where at now. Best brah!
