Twisted Growth - DWC

Discussion in 'Growing Marijuana Indoors' started by jazz77, Aug 17, 2017.

  1. Hey guys, first time posting here. I usually just browse until I find my answer, but I can't get this problem pinned down. These seedlings are about 2 weeks old from sprout and they just don't seem to be growing right. It kind of looks like overwatering, but I don't top feed and their are roots in the water with an air gap. I saw on another post somewhere about twisted growth and leaves growing on top of each other, possibly being mites.

    I did have a few light leaks that I pinned down yesterday and cleaned the entire res with h2o2 (stones also) and sprayed the roots with a light mixture of h2o2.

    Lights: Cree3590 COB LEDs 3500k x 4 (running around 36-50 watts, haven't figured it out yet) @ 24" at 3/4 brightness
    Room temp: 70-78 degrees F (70 at lights out)
    RH: Low 45% High 70% - (Generally its 45-50)
    Res Temp: 68 degrees
    pH: 5.8
    PPM: 370 (Use tap water, which is 120 ppm out of the faucet)
    Strains: Blueberry and Girl Scout cookies

    - I use the GH flora grow series, I add the micro first, then grow then bloom. at 1/4 tsp per gallon
    - Hydroguard @ 2ml/gal
    - Recently added SM-90 yesterday at 1 tsp/gal (I've heard it defeats the purpose of Hydroguard, while I also saw that the company stated they work together)

    Before lights out yesterday, I mixed 1 part SM-90 to 5 parts of tap water and sprayed the tops and bottoms of leafs really well incase it is mites. I also have some neem oil and azamax on the way. Any help would be greatly appreciated, I just keep dumping money and can't pinpoint the problem.

  2. pH is at 5.8 and my PPM is 370. My tap water is around 120 ppm, so about 250 ppm of nutes/hydroguard/sm90/any ph down residuals
