Yea I rinsed all the rocks off before they were put in the net pots. If there was any residue left from the rocks it would of made it's way down onto the roots awhile ago anyways. I am confident that the brownish roots are a result of bad water.
My PH was too high. My res water was old over a week and a half and needed to be changed. There was debris floating around in it. And the new water I used at the time was full strength nutes and the water it self was a brownish look to it. So I think the roots were damaged and looked lack luster and a combination of nute stain.
The new problem that I see that has presented itself is my res water PH keeps rising. Everyday I have to put PH down in it. When i go to bed its 5.5 when i wake up its 6.5
Anyone have any idea whats going on with this water?
