You have a picture of the whole plant?
need more than just a leaf pic...... that pic looks like it possible due to pH or nutrient related problem.... most likely ppms being too high it looks like.
 
Couldnt post till today so these pics are 5 days older then the leaf pic. The affected leafs are fried, brittle and break off if you bend them. The strange thing is on one plant that has 2 colas, only one cola seems to be effected.
Any help is appreciated.

Hey, sorry man really I am by no means leaving you hanging; I have been very ill lately and have not been able to come onto the computer; I am just not getting better.

But if there is only 2 weeks left I would go for the flush, but your plants look like they have got some form of bleaching it seems like..... if not it's a micronutrient lockout issue from a lot of nutes being involved......
 
Stitch-

Didnt mean to imply that you were intentially blowing me off, I was in a dire situation and no one helped me out when I really needed it. Not you fault, I was just venting :)

I hope you feel better!!
