I used an old bottle of a flowering nutrient, and the next morning some of the leaves were discolored and disfigured.

I'm sure this is what is called a nutrient burn, correct?
I stopped counting the weeks long ago and I use the ol' eyeball method instead. I guess I just "know" when they will be ready by looking at them nowadays.
You're welcome! Cloning is very simple. The easiest way is to cut a few lower branches near the base and put them in a cup of water for a week thereabouts. When the roots start showing, plant 'em!
I would take some clones in case it goes south. I don't really have any advice other than perhaps, since they have a while to go anyway, at least put them in a larger container so that the roots can spread further apart?
Edit: Forgot to mention that those sativa's look like they'll be a good...
What type of lights are they under and how close are they to the plants? What type of soil are you using? It looks like the soil has a lot of perlite mixed in with it, so I wouldn't imagine it would be too compacted that the roots wouldn't be able to grow? I really wouldn't feed them anything...
It won't be too long before those sacs will open releasing a LOT of pollen. If you have female plants nearby, I'd move it out of there ASAP otherwise you'll be loaded with pregnant ladies ;)
At the very least, get rid of everything in that closet except for your plant, lights and fan. Open that closet up so that more light and air can get to her.
