Pic 3 looks like burning from excessive nitrogen or fertilizer salts, rest of the pictures look a bit like potassium deficiency. It takes 2 weeks or so for any improvements to become seen in the leaves after any remedial treatments. As this plant is so close to harvest, I doubt there is anything you can do to make things look better/fix things before harvest maturity. Had you asked ths question 2 weeks ago, when these symptoms probably first appeared, there may have been a chance to improve things slightly. Anyway, at this late stage, just keep going and she should be ok, but even upping the K now, won't have any time to help.
