    Default Brown yellow spots on the leaves!!!

    Hey hi and Happy new year to all.
    I am in a bit of a struggle here i cant determite what is the cause of the yellow-brown leaves.
    I am using buffered coco with canna A+B and Pk13 and canna Boost also calmag biobizz in 10lt smart pot.
    PH watering is 5.8-6.0 Temp:25-27 celsius Humidity:45-60
    Strain: Purple Haze Auto
    But i think something is wrong with it because its over 4 months now(bad or mixed genetics idk)
    Any insights are welcome and thank you.

    It looks like lack of P, so I don't see why not. Wait until you get another answer.
