    Default Yellow spots

    Soil
    Super lemon haze
    Photo
    Around a month old
    Unsure of pot size off hand.
    Repotted a week ago.
    Soil type is verve multipurpose.
    Haven’t used any nutes yet at all.
    Air temp min 24c max 27c
    Humidity around 50%, but the hygrometer is on the soil.
    Light was 50w lightwave, just switched to 125w cfl.
    18/6, but I have been leaving the door open, so the dark hasn’t been that dark at all.
    Ph of water around 7.5.

    Only a couple of leaves around the mid to lower sections of the plant.
    Just want to catch it early whatever it may be.
    Otherwise she is looking quite healthy I think.

    Nice healthy plant, reaching for the light! looks like it's getting a little bit of a calcium deficiency are you under LEDs? Always need to start the calcium early if you are

    I think it is Leaf Septoria (early stage).
    leaf septoria is a fungal disease that attacks the leaves of young cannabis plants, typically beginning with the lower branches
    Neem Oil may be used to help combat the problem.

    Not using LED mate. Just switched to a 125w cfl, from a 50w double bulb Lightwave.

    Thanks Alex.

    I've ordered some organic virgin neem oil. Sounds like it's a good thing to have in the locker for them anyway, so 500ml en route

    Do I just spray it on, or wipe it on the leaves with a cloth?

    Cheers
