    DWC Nute Burn. Any solutions?

    Planning on flushing the rez today, but skeptical on using Clearex. Thinking about going with RO but not sure yet. Some of the new growth looks pretty healthy but some leaves are looking like they have sever nute burn. The plants are 18in and the roots are short. not a lot of them coming through and this is week 4.

    It is mid 70s in the room and the water temp fluctuates between 69-74. This is high and i am still trying to come up with a better solution than ice bagging.

    The PH is between 5.5 and 6 which is decent.

    There are 3 CFL's (cfls 26w 5700k) and one LED (ledufo 90watt) hanging at 18.5in. The lights are high and ill be dropping them shortly.

    Any solutions to the nute burn? Would love to have some healthy plants come harvest.

  2. What brand of nutes are you using?
    I have had the same issues in my DWC system. I get salt build up and nute burn/deficiency almost every run. This last time it killed my yield by half. Now I'm left with fluffy seed covered buds instead of dense nugs.

    If you can scrub out your rez and rinse the roots of all debris. Then I'd either go with clearex or light nutes for 4-7 days.

    The clearex is sugar that the plant uses to continue growing while flushing. It might also help break up any salts that may have accumulated.

    Good luck:smoke:
  3. Im using gen. hydro nutes. I think my girls have nute lock and need a serious flush.
