Messed up plant - harvest or wait ?

OK, so this plant was thoroughly screwed up from a severe nute burn a few weeks back. What's left of it has been flowering for a little more than a month. It is in such bad shape that I'm considering just taking what's on it now. Since this was bag seed from most likely mexican strain I have no idea how long it's supposed to flower but I know some of the southern strains don't take very long.
I have no experience with this so please take a look at the pictures and tell me what you think.. time to cut? or wait? How long?

Thx

flush it really good and let it grow. cut off the dead shit.
maybe give it alittle superthrive. not too much!
or smoke it!

What kind of mexican strain is that????

Flush and pray! Your about half to a third of the way through budding- there's still time for some recovery. If you harvest now you'll get a few joints. Wait and you'll get a bit more. I'd start a new plant now and by the time you poor burnt baby is done, the new plant will be ready for 12/12. - Granny:hippy:
