the more information you give out, the easier it'll be for someone to help you.

what medium are you growing in? what strain are you growing? what nutes are you using? what is the pH of your nutes in solution? are you using regular tap water? RO? distilled?

After chatting with a friend from here about it, I decided to completely drain the reservoirs and buckets. I filled up with Tap water and added about 300-400 ppm worth of floranova grow. Then I added 2.5 ml/gallon of the aqua shield (just enough to fight off root rot if it crops up). Ph set to 5.9 for all the reservoirs.
Hoping that things will bounce back and continue growing so that I can snag clones.

Any other advice would be appreciated.

After talking with a friend on here and saw some issues with drainage on the RDWC setup, I decided to eliminate many variables, and decided to do individual DWC and put them under some fluros.
Now all I have is 300 ppm of the floranova grow in these, and PH of 5.9-6.1. I am doing top drip feed for all of the plants.
