    I'm going to guess you're mixing tap water with nutrients and feeding that correct?

    Coco needs a fairly acidic pH, more acidic than soil. Think 6.0 pH. If your tap water is starting high, like 7.5 or more, odds are it's a pH issue combined with poor watering discipline and lack of light to promote vigorous growth.
