it sounds kind of odd to me that a simple re arrange of the grow space would make the plants stop growing to me.. sounds like something else is going on with them to me.. but we'd need more data to help diagnose this for you some more.. what all was involved in the rearrangement of the grow space?? what else has been going on in there, temps, humidity, lights, nutes, medium, the more details you can provide us, the better we will be able to help you out...
