Adding nutes to rdwc, ppm levels

  1. Hey. I have a rdwc system. 5 buckets, 1 for the res. I started with about 1000ppm 4 days ago. It's now about 400ppm. Do you guys add nutes during the week to keep ppm levels up around 1000?
  2. That is a very fast drop. I don't think I've ever seen my PPMs fall that fast.

    I assume that you are in mid-to-late flower and everything is looking good. I would step up the nutrient level on my next Reservoir refill and I would add nutrients back in in between Reservoir refills. This goes against general advice but it's what I have always done.

    Good luck and I will be watching for responses to find out just how bad my advice is.

  3. I adjust ppm and pH every day unless away from home.
    Probably overkill.
  4. It's the first week of flower. But these plants have been really healthy the whole time. Thanks.
  5. Thanks.
