could this be used in late flower?

Nearly forgot. Lonestar used to advocate using it for a soil drench for fungus gnats but I can't remember the rates he used for that.
Found it-Use 1 part hydrogen peroxide to 4 parts water. Fungus gnat die on contact with hydrogen peroxide. Let the top 2 inches of medium dry out, where larve reside, and then apply.
