Hello everyone, I have a quick question. I just have a good ph'd water in my bubbleponics hydro grow because they're still too small for nutes and I noticed the roots starting to turn a little yellow/orange. I've heard healthy roots are white. What are some causes for the discoloration? Any helpful knowledge is much appreciated. thanks
