  • Yellowing leaves on my Wws

    I'm a first timer experimenting so bear with me. I started seeds (Ww / SKRH) in Jiffy Peete and they sprouted nicely and just started to grow. At about two weeks, I transplanted them into larger containers. I realized after reading a lot about this that I might have made a serious mistake with the soil. I put them into Miracle Grow (6-month feed) as that is all I had available at the time. I am now experiencing yellowing leaves on two plants and one plant not doing well for the past two weeks. I cannot nail down whether it's the additive nutrients in the soil (toxicity) or if I have a real problem(s). I've checked pH, temp, humidity and everything is in the range that should be okay. I also have a Skunk Red Hair growing right next to my Ww and it seems to be doing better, albeit with some yellow on the edges of a few leaves. Any advice or suggestions to save these plants is greatly appreciated.
    Ww Yellowing on emerging and edges of leaves. Again transplanted into M.G. soil. Plant appeared relatively healthy about two weeks ago, but seemed to take a turn for the worst this past week.  Again transplanted in M.G. Not sure what the problem might be.

    Hey sooth, these dont look to be presenting any type of nutrient toxicity. Are you using lights ? What this looks like to me is light bleaching. The plant in the second picture seems to be having a extra problem which presents as heat stress. Give me some more information on your light source, setup and watering schedule.
    Being wrong, is only a opportunity for getting things right.

      Hi,
      I am using lights (T5s on 18/6). I've kept them about 10 inches away. I followed some instructions that were posted about keeping them as close as possible with these types of lights. I water maybe once a week as the containers still seem rather heavy for almost a week. I also check the topsoil until it starts to dry as well.

    Hey Sooth, welcome to the forum!!

    What is your pH in and pH runoff? Do you know what I mean?

    And YES, Miracle Gro is the wrong soil for cannabis; the soil won't give correct nutrients for different stages of cannabis. Here is why:

    If you scroll down to Myth # 1, you will see why.

    Your leaves look like these leaves to me:

      My pH is about 6 in and out. I've used one of those meters that test light, pH, and wetness. I'm not sure that it's all that accurate though. I started to use test strips and it looks like about 6.0. Thanks for those links! I guess I just have to wait it out and see what happens in this soil.

      It sounds like you're on it, so it's weird. Did the yellowing happen immediately after transplanting? Have you provided any other nutrients or additives? How long is it taking to dry out between waterings? I know it might seem redundant, but is it possible to get a picture of the plants in in their setup?

      You mention they're taking a long time to dry out, and I just wonder because sometimes "wet feet" can cause deficiency even if everything else is right. I recommend giving them half that amount of water at a time, in a circle around the plant, and see if it dries within about 2-3 days. If it's taking longer to dry, give even less water at a time. If it's drying in less than a day or two, give more water at a time. I just wonder if giving it a touch less water will help it "get going" and you'll be able to water it normally again.
