Indoor grow, Coco, H3ad's modified Lucas formula, 600w HPS, 6th week of flowering I have grown about 10 different strains using the above setup without any real problems. However I have one strain, Amnesia Haze, which has shown the same problems two grows in a row. Brown coloring spreads through the leaves starting at the leaf base, the flower at the end of that stem stops producing new pistils so it appears the flower has completed it's cycle as all you see are orange pistils with no white. I'm having a problem determining the actual cause so I'm not able to develop a treatment. I was hoping someone here would know what's going on so I can make an adjustment. I do add 2 grams Epsom salts about once a week to my four gallon mix bucket. I thought the problem might be toxic salt reaction but I'm not at all sure. Any help or insight would be most appreciated. Thank you!
