    Default Potassium Defiency

    Hi guys

    Few of my plants have some interveinal yellowing on the lower plants, it isnt very bad and has only got a tiny bit worse over the past week... I have come to the conclusion through process of elimination it is a potassium defiency due to the circumstances...

    Potassium deficiency (K).

    Older leaves are initially chlorotic but soon develop dark necrotic lesions (dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken, the plant may also stretch. The plant will become susceptible to disease and toxicity. In addition to appearing to look like iron deficiency, the tips of the leaves curl and the edges burn and die.
    I am using batmix, so this may be one aspect and have a pretty hard water level with alot of CaCO3 which is another cause...

    I cannot waterfeed really due to the high levels of fertilizer in batmix so a feed would surely give me burn and i dont quite have the money for a RO system lol....

    Does anyone have any suggestions as to how to fix, i have though about a foilar feed to correct the def as my only option really

    Note: i havent uploaded pictures beacuse i have come to my own conclusion of what the problem is, i just need to know how to fix it

    Potassium Sulphate in salt form may work mate, it is water soluble so can be applied to the plants when watering without providing any further nutrients to the plant.
