thoughts on my leaf problem

I recently had to be away from my ladies for a week and one of them experienced a ph lockout while I was gone. I returned to find about 3 rows of leaves stemming down from the top severely curled with many patches of dull green or orange. Now it's about a week and a half later and i've gotten her out of lockout and the leaves have unraveled, but the spots have progressed to brown and probably take up about 50 percent of the leaves' surface area. I was wondering whether you guys had any thoughts as to whether I should leave the damaged leaves or cut them off?

If they look like any chance of recovery, save them. Wait until they are so near dead, you know 100% sure that they will die, then remove them.
