This seemed to happen over night. Last night I left the water pump off. I check em just now and there brown like this. I'm on an 18 light 6 dark cycle. they didn't seem to grow last night. The roots don't seem mushy but they were white yesterday. My water isn't crystal clear but it hasn't been since I got em and been worse than this. I put the water pump back on. Maybe this will fix it. Any other ideas? Can I clean the roots? It's not the clearest of pics but any help is appreciated.
maybe you just caught the beginning of root rot just change out the res nutes and dont let them get so dirty, if it gets any worse you may want to try ClearX you can get it at most hydro shops
