    Question Yellowing of plant :(

    I'm having a few issues. All of a sudden my bottom leafs have started to turn Yellow and I'm not entirely sure what the cause is.
    Does anyone have any ideas?





    Thanks

    (FYI - I made a typo in the post title - if a moderator could fix it I would be grateful!)

    It helps to have a lot more info like medium and lights and temps and feeding schedule but my guess is she wants some food.
    The set of leaves above the bottom are also starting to yellow implying nitrogen deficiency.

    LED's mate, but I've just had my HPS delivered today which is dimmable - do you think it's the lack of light? I do have like 8 plants under a 250w LED? (purely because I expected two to die lol)


    Thanks

    I was thinking either light or feed... looks more likely to be feed now....

    Do you think I might be underfeeding them? The one I planted a week later than the other is doing so well and I was throwing water into that.

    I had the same issue on this grow-Using LEDs for the first time. Seedlings need to be quite far from the lights until they toughen up a bit. I switched to CFLs for a few weeks to let them grow on and the issue went away. How far up are the lights?

    I'd say about 60CM - 70CM away and it doesn't seem to hot and the temp is around 25 - 29 as well.
