So I don't know what's going on with the little brown bit in the roots, but it's not spreading and the rest of the roots are still growing in nice and think and look very healthy so I'm willing to accept a cease fire because nuking it with h2o2 has been making the fair lady upset.
This plant has been growing very thick and short and I gave it a substantial defol to open up airflow and I raised the light a fair bit to encourage a little more vertical growth so I can start scrogging. Aiming to flip in a week or two.
