I know youre not supposed to water with tap water because it causes build up of all the impuritites in the water. But will watering organics with tap water kill of microbes? Im not talking about the whole grow, just watering with tap once or twice. I ran out of distilled and was really tired and didnt feel like going to the store, so I just gave her some tap water. Shes looking pretty crappy, but thats because its the end of the grow. Im just curious if I did any harm. Thanks fellers!
