Azamax and Nutes

Has anyone used Azamax mixed in with thier nutes as a root drench for fungus gnats? Guy at hydro store told me it would be fine but directions dont say if you can. When I mixed it in with nutes and adjusted ph my ppm went from 1300 to 1550 so im wondering how bad of a burn im gonna get. I know I should have added more water to bring ppm down but was running late for work. Think I should do a flush just in case or just wait and see if any signs of nute burn?

Hopefully the plants won't uptake the Azamax at all. It never hurts to lower the PPM so to be on the safe side I would advise that. At any rate the Azamax should not burn the plants.

Thanks for reply. I think the GH ph up Im using caused the ppm to go up though, I dont think it was the AzaMax but I could be wrong.
Does anyone have the same with ph up increasing ppm ? Just wondering if this is common.
