EBB AND FLOW VS. DRAIN TO WASTE

[SpaceNeedle]

I JUST SWITCHED FROM HAND WATERING DRAIN TO WASTE TO EBB AND FLOW BUT HAVE NOT RAISED MY PPM'S. SHOULD I? RIGHT NOW IM RUNNING 6.0 PH, 1400 PPM WITH GH NUTRIENTS. ONLY A WEEK LEFT BUT IM WONDERING IF I COULD HAVE PUSHED THEM A LITTLE HARDER.
THANKS

I do ebb and flow, and I seldom ever have the ppm's even at 1400. Then during the last 10 days, I flush the plants with water. .... and you're asking if you should raise the ppm's near the end? The plants will only take what they need/want. Try setting the ppms on your next grow, say at 1000 ppm without drain and waste for a week, and then measure your nutrients. If your ppm is 800, that means your girls have been using MORE than 1000 ppm, but if it is more concentrated, like say 1300 ppm, then it tells you your plants are drinking more water, but not all the nutes you are dishing out.
