Overwater or Overfert?

Hi, mi plant has a dropping leaf prob on the top...I can´t tell if its watering or nuts, help plse, here are some pics:

i have something similar going, probably not over watering or nute troubles
maybe a little warm, some strains make curved leaves at the top, overall looks fairly good

Not enough light is the reason.
