Carefull with messing around with light cycle, MJ's a photo period sensitive plant, anything less than 13 hours of daylight can induce flowering and the change in hormones could stunt the healing process of the roots.

Leave the lights on, perhaps unscrew one of them to soften the amount of light hitting her.

Make sure your not over watering! Over watering will cause the leaves to droop, and will suffocate the regrowing roots. Roots need a certain amount of air to breathe.

As for the root stimulant,.... I would hold off on that until you have a healthy root mass to up pot, most of those are intended to help the plant shrug off minor up potting stress,... this isn't minor, so stimulants or ferts would probably do more harm than good. If you feel it's something you have to do, go ahead with it, but ease into it, 1/4 strength or so.



Calm down, step back from the plant and smoke a bowl. :S5:
