Ppm Won't Go Down

[420 grower]

I have a 55 gal res. ebb and flow. When I change water and feed nutes the ppm goes to about 1400. A week later and two weeks later it still tests at around 1400... Any suggestions?

Sounds like your doing it right to me...Your plants are using an equal amount of water and nutrients...If the strain wants more nutes it will take them and your ppm will drop...I like to push it a little and ramp the nutes up just till I see a little leaf burn at the tips of the leaves then back off a touch.....HJ
