I have a girl that's in her second week of veg. She was growing real strong and healthy and I change the water out every week. She is in her own individual hydro bucket. I noticed te other day she started to droop. I change out on the weekend so we I did the change I saw her roots were a light brown. I cleaned out her bucket really good, ran fresh water through the sprinklers with hydrogen peroxide for a bit. Then changed out water again and did the routine. This morning as I was ph'ing her water, it was at 6.3, so I brought it back down to 5.8. I'm using Dutch pro and I don't want to lose her, she is my last ww. I cleaned off her roots a bit and changed her air stone to a new one. What else can I do? I lost six plants to root rot when I used to use a big tote to grow. Now I put each in their own individual bucket and this is the first one since to show signs. She is in a five gallon bucket sitting in hydrotron.
