Hey, I'm in my 3rd week of veg and I added 3% H2O2 (hydrogen peroxide) to my reservoir to kill some of the bacteria I noticed, as well as add some oxygen to the water. After adding I balanced the ph at 6.7, my super silver haze loves it around there. Cal n mag levels are normal, not sure what's going on. Was fine 6 hours ago... Please help.
