Plants reacting to shade or no light

I have been leaning over two plants (taken from 3 week flower current age is 5 weeks) to work on some plants. I should add they are doing very well and are in very good condition. They are under HO T5's. They are shaded while I am working for say 5 minutes and then it looks like someone let the air out of them? They are in 6 inch rockwool cubes and are not under watered. I put the lights back down and a half hour later they are all perked back up? WTF?
