Gorilla Zkittlez DWC

Discovered I had root rot by the 3rd. I ordered hydroguard but it didn't arrive till the 9th. I also had my plants in a bucket i had painted the inside black. BIG OOF, i know. Anyways i bought new all black buckets from home depot on the 9th of June. So this week she was just stressing and dying. I cut off most of the dying leaves and clipped the ends of the ones dying but thats all shown in the next week pics.
