Emergency ! Save my plants please !!!

Hi,
I must do quick, every minute saved could make the difference...
To make long story short :
- Just got back my plants that I left to a friend because I was away for a few weeks.
When back i noticed huge space between nodes (not enough light) and leaves showing signs of under-watering.

Just put the plants under 400 HPS and made the mistake to add a little bit of some kind of fish fertilizer (for fruits and blossoms)...
The plants now look like on the pictures.

I need to know if these are the symptoms of over-fertilizing or only water related problems (too much of it) because if it is fertilizer related, I need to flush, but if this is the sign of over watering,,
I think flushing would be the last thing to do.
Please tell me what to do.
PS: Those are Super skunk from Nirvana from which I just cut 6 inch main bud because ridiculously long stem ...

Here are the pics :

Yo I cant tell for a 100 percent with those pictures but looks like you got a male. They tend to grow real gay like that. But i am pretty sure about this other people pleas post I want to see if I am right.

What kind of soil are you using my friend.

It very well may be a male I had one grow all akward like that. Usually with over watering you would see heavy drooping in your leaves. Is there any chance you could take a close up pic really can't see to much from afar.

Too much water for sure, most def. a male, or some horribly stunted sativa strain, due to lack of light. I'd go straight with water and see what happens, dont waste your nutes on what could be a male. Light deprivation seems right for why you have such spacing inbetween nodes. Cross you fingers for good results!

Guys click on the pics and you ll see it is a female 100% buds :d
