well I have my first dwc setup and they were doing soo bad ass and now the roots are turning brown and they arent perking up anymore... what is the deal? I added h202 at 4ml/gal 29% h202, still no improvement , I ordered hygrozyme last night so hopefully that will help? What could be the cause ? I have water temps at 67 and use GH grow, micro and bloom with cal/mg and superthrive. I added great white for 5 days once , maybe that was it?
