Dr. Needed! Slight Screw Up, Pics Included

First off, thank you for your help in attempting to walk a newbie through his first major screw up! Here is what happened.

Aeroponic Setup - 4 Gallon Rez

I started to run out of water toward the end of my 3rd week of veg. About the same time I realized the water was running low, I had just finished up my 3rd packed bong and was in no way ready to drive to pick up distilled water.
To make matters worse, I did not have any water evaporating out at the time.

What did I do?

I shut the pump off during the 6 hour lights off period... At that point, I got some water from the 2 pitchers of filtered water I had in the fridge. I pHed it to 5.5 and added it to the reservoir. My girls started to really complain.. WoW A day after I noticed them drying up, I introduced them to their regular feeding schedule with some tap water that was evaporated for 25 hours. pH at 5.7 and PPM at 670ish. (Around there, I need to calibrate again)

The girls started to come around, but not fast enough for my liking. My big girl, up front to the right, has some serious leaf damage and they are very dry. New growth seems to be slow on all my girls right now....

Here are some pics of my damaged babies from this morning:

Should I clip the dead leaves... What is the best method of doing this?

Other suggestions?

Thanks for all the help!

Does it make sense to lower the nutes down to nothing to relax them a little?

Dude, don't let your plants go without water... They are not that sensitive to regular tap water. I would not worry about lowering your nutes.

Should I prune the dead leaves off, or let them sit and see if they recover.

1 light cycle of 18/6 seems to have made a big difference in most of the girls. The big fan leaves are still pretty bad, but new growth and stem thickness have increased since i last took my picture 12 hours ago. Amazing to see that kind of growth before my eyes. Still wonder if I should get rid of the lower leaves that I might have killed/burned/dried out.

Your not going to hurt anything by removing them. They will prob dry out and drop off anyways.
