help before it dies

what could be the causes of wilting..
most of my plant is wilted its been this way for a few day
Its outdoors on 15/30/15 nutes for about 2 weeks since the rest of the crop started flowering its about 4 months old in a five gallon bucket by itself
it's not from over/under watering
the rest of the patch looks fine and they get the same treatment..
what does root rot loook like i read one of its first signs is wilting all tho the bucket has adequate drainage
dunno its just wilted real bad its 6 foot tall and all the males popped awile ago so i'm figuring its a late flowering female
last time i posted his noone said anything
NEED HELP

I am not an expert but if it isn't over or under watering then it may have something to do with the amount of nutes you are using, is it nutrient burn or is it just wilting? Or it might even have something to do with the temperature being that your plants are outside. It's too hot is some places during August.

its not over/under watering they have all received the same amount.. If it was that would some or all of my plants would be showing signs of it....
It's just wilting

Hard to tell without a picture. Could be a lot of things.
