  1. I have a small grow going of 4 plants with only one plant developing brown spots starting in the older leaves and working its way up tarting at the leaf tip. I have attached some pics.

    Its a DWC grow using the lucas method.
    600ppm @ 5.7-5.8ppm
    Strain = Critical Jack

    Any help would be appreciated.
