whats wrong with her...

here are some pic of my lady and she was doing so well but now I dont know what happen...she is in her 7 week of flowering, the temp is at about 78ish when lights are when off its 65ish I have a good air circulation and she is on a 11/13...please let me know what I need to do to help her get healthy again so I can smoke her and love her...
first three pic are what they look like today and the llat pic is of her last week...

either too much nutes, or over/under watering.

cant give you a definate answer, have you changed its enviroment or schedual recently, if it was well before and now its not, its ofton through not increasing what it needs, or changing its enviro.

how about more details. that plant looks like hell in all the pics. i don't see a plant that's been flowering for 7 weeks.

A little slip of whiskey always did the trick mega lol but yeah it could be over or under feeding/watering.
