I would dump your rez, sterilize it and start with fresh H2O and Nutes. Do you have somewhere to park the plant while you clean up the rez? They will be fine out of water for an hour or so. Or you can rest the net cup over a bucket and let the roots hang in water. Either way, she'll be fine. I would CAREFULLY flush out your roots too, make sure you don't miss any of the little fuckers....Peace
