Over a 4 day vacation, my water pump on my hydro setup failed. The plants have dried out and flopped over. They were about 8 inches tall at the time. All the leaves are flopped over and curled up and a lot of them are starting to turn yellow. The stems still look green though. I turned off the light and water them instantly. I placed a new pump in the setup and they have gotten water for about 12 hours. There isn't a significant change from when I found them to now, but I hope I can save a few of them. Does anyone have some advice to help me save them???
