    Default Can anyone ID the disease please

    Hi one plant has burned tips and get worse slowly. Its not nutrient burn. I suspect its excess potassium but would like someone elses opinion as this is my 2nd grow
    The first 2 pics are bcn critical xxl auto and the second 2 pics are BlackBerry gum auto. They are getting the same nutrients the bcn critical seems to be putting up a hood fight against the disease compared to the blackberry.

    Thanks in advance.

    What makes you so sure that it's not nute burn? What nutes are you using and what medium are you in?

    I'll tell you now it's not disease. It's over fertilisation. If you are giving both strains the same strength nutes and only one is showing stress, then reduce its feed strength.
    When you do things right, people wont be sure you've done anything at all.

    Plain as day as above members are telling you..those tips are burnt through overfeeding, dial back now or it will get worse in my opinion.

    The reason the tips burn is literally the plant putting the excess nutrient to the least important part of its "body", which shrivels and dies, ie the leaf tips
