HEY THERE ALL AND PEACE! This is a White Widow Strain. Mother showed signs 2 weeks into flower. Pretty much all the leaves became necrotic including bud leaves by the time it was harvested at seven weeks. Clones of mother showing same signs.only 2 months old including clone time (rooting took about three weeks). First destrys shade leaves then attacks bud leaves and smaller leaves last. Both the mother and its clones have the same problem except clones show more advanced stage of disease/nute prob???? Using Black gold medium. My B-52 and Kahuna's are flourishing - no probs here! Never had any probs with BG. Thanks all. Appreciate your help! B.
