yea most likely,u prob sent it into shock,pull the lights away about double the distance they are now and dont mist for a few days and they should bounce back with a vengance
very doubtful, that its over watering,its a shock that theyre in,i get that some times and its a bitch to fix bc it tends to mask itself as another problem but its a simple fix.
having the lights a distance away will prevent it from goin into catastrophic shock. the flowering will be delayed by a few days since theyre in shock,but it wont be noticable. if u keep the lights on top as normal than it will cause the plant to basiclly shut down all vital functions bc they will try to absorb energy while being in shock causin yes actually having the roots work in reverse and drain the plant of nutes and water. then u will have a dead plant. when a plant goes into shock its not hard to get it out of shock but it is real easy to finish it off and put it in the grave if u do the normal activities with the plant.
