    Hey guys I have a really strange issue with my plants.. Zero growth over the last 3 days... I mean none at all... Just 4 days ago they were aggressively Vegging... They're basically frozen.. I have grown for years and never seen anything like it... The day they stopped growing was the exact same day that I did a nutrient swap and trimmed. I literally only cut Four Leaves off of plants just above and below their sixth node. Each one is in a DWC.. PH 5.8 ppm 600 including 130 from the tap. I'm at a loss... SOMEBODY PLEASE HELP... These are my first Glueberry OG that have ever done this...

    Any help is greatly appreciated. Almost positive this is nute burn tho. Just bad on this leaf for some reason. A few other leaves have the signature nute burn on the very tip but this one has it bad. I think its spreading too. Should i cut it off? Im using kind soil (hot soil) with no added nutes. This happened a few days after transplanting to the hot soil which is why im sure its nute burn. Sorry for my shitty camera. The first pic is the bad leaf the others are just the tips.

    Just cut back your nutes
    Flush it, and pray.
    You'll be golden mate.
    Let us all know how it goes.
    Good luck

    Thanks for the good luck wishes lol. Im not using nutes tho its in super soil. Pretty sure the soil is just too hot but the people at kind soil (the company i bought the soil from) say that'll happen if you transplant into the hot soil too early and they will grow up and be fine. So im gonna ride it out and hope they are right lol. Just wondering if i should cut that leaf off really.

    i'd give that a little flush, maybe 3 gallons of ph'ed water, then keep an eye on it, the roots ought to recover pretty quickly, but if it doesn't stop spreading, you may want to do it again. once the roots heal up, the whole plant ought to look better pretty soon

    Im thinking this is a ph issue. Im using kind soil (hot soil) its an organic super soil with all the nutrients my plants will ever need. So i know this isnt a lack of nutrients. Lockout possibly but the ph of my water going in is 6.5. You aren't supposed to water to runoff with this soil so i cant really test the runoff ph. Any ideas? One of the plants (critical) is barely effected, the other plant of the same strain looks like shes about to die. The cookies plant has some of the leaf issues on the lower growth and the bottom half of the plant is droopy. Top half looks healthy tho.

    Id get a ph stake (my favourite, they sell ones for ppm as well). A soil testing kit. Or, you can mix a sample with distilled water, to test with your probe.
    You'll be able to find, the amount of distilled water, to soil on google. You can check ppm, this way too.
    If you take samples, of soil. Dig a little deep to get your sample. Get a sample from the bottom of your pot too, and compare it, to the top sample.
    IMHO, judging by the bottom pick. You may be better off transplanting, into something gentle, with lots of aeration, and drainage. Then really watering it in, with plain water. The largest plant, is pretty close to a new pot, as is.
    Just check all your soil first. Something's going wrong. You need a good idea of what first.
    Iv'e found in pots, its usually the bottom, thats troublesome. Which may be likely, if you havnt been getting runoff. Because sediment will, wash down and build at the bottom. It could be high ph, fom lime etc. It could be low ph, from fertz or manures, or rot. Ph could be fine, and its just hot soil. You need to have a good idea to act on.
    Good luck
    Best wishes.
    I hope you find your problem.

    I have one of the 3 way soil probes that test ph and moisture and light but i was under the impression that those didnt really work for ph and people mostly just use them for moisture. So i didnt even try to get a ph reading with it. I think ill get a soil test kit and dig some of the soil out. Thanks for always jumping in to help tim. I'd burn a fatty with you if i could haha

    No worries man.
    They're pretty handy tools. They can just be a little unreliable, so i buy 2, and check their accuracy. Tbh, i havn't bought many faulty ones. But i still always check.
    Good luck.
    I'll burn a fat one for you, give you Mary Jane's blessings. :bigjoint:
    Thanks for the kind words,
    Best wishes
    Keep us all updated.
