Sorry for not putting this thread in 'problems'.

I'm not seeing any improvement yet. Not sure how long it takes. One plant seems to have no roots in the basket area and what roots there are are like dried brown hairs. Almost like the problem started in the hygroton area? IDK. Right now I have 4 plants. 2 are tall, 2 are short. The short ones have stopped growing and there's some yellowing at the bottom. Only one has a great root system which is odd to me since the buckets are all linked.

I'm going to pull the plants/baskets and scrub the buckets with bleach, add a 900-ish????? ppm of nutes and the peroxide. To add insult to injury, I found out today that my hps was on probably 24/7. I think this only occurred for a day or 2, but I'm not sure.
