wilting leaves

[rastamonkey]

Im growing my first plant and everything has been fine up until a few days ago when the plant started to wilt. Can anyone give me some suggestions as to what to do.

Is that outdoor ? Has it started to get cold recently ? Cannabis plants kinda curl up when it cold, i had one outside during the winer last year just as an experiment. Its leaves would spread out during the day and wilt and curl inwards at night when it was cold. If the plant is indoor it may be too hot or you are over watering.
