Hello new friends

What's good everyone? I'm new to indoor growing all i know is what I have read in a few books. I have a lot of questions and welcome all input. I picked up a few clones off a friend. I am growing them in a thirty gal storage container under a 600w hps. I am using Hollands secret nutrients with cal mag plus in ro water. I added h2o2 last night cuz my water temp stays around 72-73F. This morning my roots have a brown tint to them is this good or bad. Please help

For real no help
