    A pic will help with the diagnosis dear.

    How old is this plant is it vegging/flowering?
    What are you feeding and at what ec ?Whats the ec of your water?
    Raise ph a couple of points.
    If 23 is room temp it wants to be warmer.26/27 works for me.

    is an auto around 3 and half week old,still veggy (ahah) but is starting to flower , the EC tester is broken and I am waiting for the new one.
    I was thinking about calcium that couldn't be absorbed because of the low ph, so I am slowly raising to 6,3.
    I just uploaded some while you were writing
    thanks mate!

    It all started from the middle of the leaf and then spread to the rest of the leaf, but is only limited to the "sunny" area.

    what feed are you using?

    Cant really see under the led light,daylight pic would be better.
    Without measuring ec its hard to know if youve been under or overfeeding.

    If its not near a fan getting windburn and it hasnt had any nutes spilt on it id hazard a guess at phosphorous deficiency.

    hi bayweed welcome to the forum

    well im gonna have my noob diagnosis and say its ph drift and nothing to worry about ............... reasons are as follows

    your first post you say your ph was 5.5 and you have been lifting it up to 6.3 slowly in your next posts . im gonna take a stab and say A: you did to much of a jump or b: your drifting it to quickly manually .

    i had the very same browning on my leaves on my grow the now which is first time dwc (not my first grow) and it looked very very similar to yours .only 1 or 2 leaves had it rest of plant and other plants were fine in the same res .
    my diary check from page page 4 post 76 :https://www.thctalk.com/cannabis-foru...-pinkman/page4

    check this out age 2 post 37 https://www.thctalk.com/cannabis-foru...y-thread/page2

    just carry on as normal and be careful with your drifting of ph would be my diagnosis .

    hope this helps and good luck with your grow
