Hanging a U-ie, Hopefully

Today we implemented all of the changes that were recommended for our system.  We also altered our timer so that it would operate, it had been running non-stop before.  Only one of our plants is still green and healthy, the rest appear wilted.  We also checked the pH of our solution and it looked to be between 6 and 6.5 which was well within our limits.  Hopefully we have made the right decisions to turn our plants around and go back to our initial success.
