I get my instructions from my hydro guy so I parrot them.....if you feel another dose would be appropriate go for it. Just saying......that's the way I was taught to use it.
Weedhound Reviewed by Weedhound on . Rinsing root system with H2o2 solution When I mixup a solution of H2O2 and water the Ph lowers to 3.2. Should I bring up Ph to normal levels 5.2-6.0 or should I leave it at 3.2? Will H2O2 solution work if Ph is raised? Rating: 5
