    I switched to flower about a week ago, tips of new leaves started curling a bit. I tried to illiminate all basic problems like light intensity, heat, humidity, PH and so on(they were mostly ons spot) My only guess now is nute burn but i have other plants together in the same rdwc and other plants are fine.

    Any thoughts om what these symptoms are?

    P.S.
    I have another plant which started off with the same symptoms, i treated it as nute burns and flushed it and gave plain ph adjusted water but just got worse. Its been about 6weeks from the point it started showing mentioned simptoms , still alive but not growing anymore. She is the one in the last attached image.

    Take your pics under normal light.

    The one that is looks like poisoning.

    However, you say you have other plants that are doing fine?

    Could be contaminated nutrients or the nutrient was not mixed well enough when added and the soup got a big dose of one of the chemicals.
    How old is the stuff you are using and what brand?
    What materials is the soup in contact with?
    I remember having a poisoning problem a long time ago when I had some copper contact with the soup.
    Kinda looked like what you have there.

    The "problem" is the cure will not repair damaged growth, so it will still look funky after you fix whatever is wrong.

    Welcome to having russet mites. They are one of the most difficult bugs to eradicate. Get out your jewelers loupe or microscope and look under the leaves. I bet you a weeks pay that you will see microscopic maggots.
    If what I just said is true, you need to look in to micronised sulfur that you spray on. This can only be applied in veg or on clones.

    Since you are in flower there isn't much you can do. Chop those dirty bitches and spray the grow down with sulfur. Start fresh and avoid cross contaminating your grow in the future.

    Sorry
