how much hydro jucie do i use to incease my ppms or what bottle or bottles do i use. i use general hydro.

That depends on what product from GH are you using?

There is a chart in the FAQ for the GH 3 part mix. If you are using another product from them check their web site for mixing instructions. They should be on the label as well.

The PPM will vary with the amount of nutrients you use, I hope you have a good Ph and TDS meter so you know the proper level's.
