    what're the npk % on them - you need to stop feeding them. you're burning your plants
    from what i can tell you have Nutrient burn, and nitrogen toxicity

    Before they possibly steer you down a bad road lol, can you post some more pics of the whole plant visible? That seems to be a leaf that maybe got ripped or touched water, surely not a nitrogen toxicity! lol

    Hi Sean,

    I'd tend to agree with nitrogen claw.
    I'd tend to agree with overfeeding. It's a very young plant.
    I agree, we need your NPK% total.
    I'd tend to agree that more pictures will help.

    Few important questions of my own-

    What is your medium?
    What is your watering schedule?
    What is the ph of your medium?
    If hydro,
    What is the ph of your water?
    What is the ec of your water?
    What is the ec of your feed solution?
    What is the ph of your feed solution?
    What is the ph of your waste?
    What is the ec of your waste?

    If you don't know any of these, and you can't find out, please say so. It is useful data regardless.


    Clawing like you see, as far as i know, is ALWAYS due to an abundance of nitrate. Now whether it's caused by an abundance of something, or lack of something else, or just an abundance of nitrate in your NPK, we don't at all know, until you provide some more data.

    Also it's very important you describe your watering habits, and frequency. Because continuously wet soil, will produce nitrate in the form of ammonium, urea etc. Nitric acid also causes ph to fall.

    My thoughts are, you are probably overfeeding, on top of watering too frequently. Personally i'd cut out the nutrient for now, and only water for a couple times until it improves.

    But nobody here, including myself, can definitively guess, until you provide a better picture and more data.

    Peace.

    :peace:

    You tell me what's wrong about it?
    Instead of criticism. Use your brain, experience, and contribute. Instead of trolling people hard, like you usually do.

    What is your own solution to this problem coco?
    What is your own advice given the supplied data?

    Stop being unhelpful.

    Please tell me what is factually wrong. Debunk the info.

    My advice would be not to take the advice of someone that clearly doesn't know what they are talking about such as yourself,it doesn't take much brain power to work that out.

    "Clawing like you see, as far as i know, is ALWAYS due to an abundance of nitrate. Now whether it's caused by an abundance of something, or lack of something else, or just an abundance of nitrate in your NPK, we don't at all know, until you provide some more data."

    ^^^ this,did you read this dribble before you posted it ? First you contradict yourself,then you re make your original statement again and ask for more data,what are you going to do with this extra data ?



    Also it's very important you describe your watering habits, and frequency. Because continuously wet soil, will produce nitrate in the form of ammonium, urea etc. Nitric acid also causes ph to fall.

    ^^ You don't even know what medium he is growing in and how does wet soil produce Urea ?


    My thoughts are, you are probablyoverfeeding, on top of watering too frequently. Personally i'd cut out the nutrient for now, and only water for a couple times until it improves.


    ^^^ If the guy is in Coco you've just advised him to do one of the worst things he can do,you should never ever give straight water to plants in Coco.


    If trolling means pointing out that someone is a bullshitter once again like yourself then trolling is what I do. If you think giving advice that is wrong is actually helping people your either stupider than I thought or delusional.

    Buddy,

    You are one angry, spiteful individual.

    I'm gonna state my point again, ONCE MORE.

    Because you deliberately left some things out which i mentioned. Or you completely missed it.

    A. "What is your medium?" (missed this)
    B. "What is your watering schedule?" (missed this)
    C. "What is the ph of your medium?" (missed this)
    "If hydro-"(missed that bit too)

    Mate. If by contradiction, you mean emphasizing that it may be many things, then you are reading correctly what i'm suggesting.
    Is it lockout, antagonism, or NPK ratio? You tell me. Take a guess.

    ^^^^ Exactly my point. I don't at all know what medium it is. Neither do YOU.

    Here's some scientific information about urea- https://www.sciencedirect.com/topics/earth-and-planetary-sciences/ureas

    5 minutes on google found this. Plenty more too. If you'd like to further argue how urea naturally occurs in soil. Then take it up with them. I'm a gardener. Not a biologist.
    Although, if you are going to suggest there is no such thing as aerobic, and anaerobic root zones, then you sir are ignorant.

    As stated, we don't know which medium it is. To assume otherwise, is foolishness. You gonna water promix or soil 6x per day?

    Just as i suggested at the bottom of my post, NONE of us know what it is without more data. I'd start with medium, ph, ec.
    Where would you first start?

    No.
    Trolling means you're twisting what i'm suggesting to suit your own argument. Your a madman.

    You are the bullshitter buddy. You are more pissy than the urea in the manure, you use to amend your soil.

    Leave me alone. You pathetic bullying child.

    Peace :finger:

    :peace:

    Little passive aggressive Timmy,if you weren't so pathetic and cringy your long winded replies would be funny but they do confirm you know fuck all about soil chemistry and plant biology other than what you have managed to find from Google search.

    YOUR ASSUMPTION THAT I WOULD WASTE MY TIME TROLLING A PIECE OF SHIT LIKE YOURSELF IS LAUGHABLE .YOUR CHILDISH TANTRUMS AND FAUX HIPPY ATTITUDE ARE A SIGN OF A SAD INSECURE FANTASIST.

    I could go on to correct more "facts' from your last post but at the rate you post false info I'd be here all day and funnily enough for a weed growing forum I've got some growing to do,maybe you could try it one day ?

    Adios Little Timmy

    P.S good luck getting all that sand out of your vagina :)

    Hi guys I was overfeeding it with nutes I have flushed and just feeding water set at 5.8 ph when flushed the ph was 4.8 I was watering every 2 days now will wait till the surface becomes dry. This is her a day after flushing seems to be ok will update on mon or tues

    Tantrum?
    You called it "bunked info".
    You state i know "nothing" about soil chemistry. Yet when i challenge your argument by asking a question, you can't answer it. Yet you ignorantly say you know better, but won't explain as to benefit the thread. I've stated my argument, and backed up the theory. Want more evidence? I can do some searching again for you. Maybe a wiki? Or .edu?

    By all that garbage you just posted, only further proves my point.

    Imvho your an ignorant, angry, selfish, rude, spiteful little brat. An unhelpful one too.

    Adios ignoramus.

    Sean,

    Great news. Glad you found your issue.

    Apologies for the way i've responded to a couple comments. But i feel it's necessary to back up, and defend what i say. Especially when challenged in such a rude and disrespectful way.

    I'll tag this thread. Will lookout for your update.

    The data is very useful for others to know. But looks as though you have things under control.
    Imo, come Monday or Tuesday, if the plant is still looking much better, i'd probably just state the medium your using, and state what you did to fix it.
    This will really help other growers like yourself with a possible solution. Might even save a few people creating a thread to ask for help.

    Peace.

    :peace:

    Your plant is looking fine; don't sweat it. One leaf, regardless of its condition, is not an indicator for the whole plant, especially when it's a seedling leaf like you've shown. I would also point out, even though the 'claw' is a good indicator of a N excess, it is not 100% correlated. In my own experience I've had strains that would show a claw and yet also show it wanted more N. The game of growing / farming is to put as many dots down on the paper and then, through good ol' logic / common sense, make the connections slowly and purposely. Your grow is fine; steady goes the course my friend.

    taking into consideration the nutrient burn, there's almost no doubt in my head that there's excess N.
    he just needs to chillax with the nutes and stop doing so much for his plant and he'll be fine.
    edit - at this point, his plants will be fine, he's done exactly that, with stopping the nutes and flushing. just eneds to get that ph to 6.5

    If im being honest here, i feel the OP has things under control. Not knowing the type of medium, i believe, still makes it difficult to determine whether it needs to be fed nutrient, watered frequently, ph adjusting etc.
    Though it does seem, as though the OP has used their own data, to form their theory, and act on the basis of the data they have.

    I'm personally gonna reserve giving anymore advice in this thread, until Monday or Tuesday. Even then unless a question is asked, if the plant is still nice and green, i won't be giving advice. I'll be asking OP how they fixed it.
    Never a bad thing to ask. Easy to overlook the basics, even seasoned growers who have been doing it for decades.

    Anyways. Imho Monday or Tuesday is a great time to pick the OP's brain.

    :peace:

    He was actually right. There is either an abundance from being given too much or an abundance because another nutrient is either lacking or too concentrated. If you wanna argue with someone replying to a post, do it in PM and stop clogging up the OP's thread as I doubt he wants to hear this.
