I havent needed too much 'till now

I cant take a picture at this moment but, my plant is in week 7 of 12/12 and was doing great even this morning it was great until tonight when i came home a few minutes before lights out and noticed the whole plant is drooping, branches are all of a sudden too heavy and i think so many branches folding at once or getting heavy has started the plant to start dying. i cant get in there to tie up branches until the lights come on in the morning, my question is if i cant get this to turn around and fix it , should i chop now? i mean i dont see another option but if you do please throw me a bone. ill humor all comments at this point. thanks in advanced

Make sure it doesn't just need to be watered.

Thats what i did with the last few seconds of lights on.

It depends completely on if the plant is salvageable and the strain. Is it an early flowering 8 week strain? or something that takes a great deal more time? Photos will help a great deal.

I understand the plants will go a little droopy in anticipation of lights out and droop while resting in the "off" schedule. Maybe you'll be pleasantly surprised at lights "on" to see them reaching again??? Keep us posted as I'm curious if this is true.

I will post pics in the afternoon when lights come on
