    Been in the cloner for 2 weeks..at least. It definitely has roots.
    Just wondering if this is a nitrogen deficiency or possibly silica?
    The water in its 'res' is 5.5-6.0 pH and has a very light solution of veg nutes (pureblend pro grow).

    hydro-coco you want a ph 5.8-6.2
     
    5.5 is a bit low.
     
    If its soil 6.5 in nominal.

    I cut a water bottle in half and stuck a small net pot in it. Then I stuck some coco in the net pot and I filled it all up with pH'd water.
