BioBudsanswered grow question 4 years ago Your plant looks otherwise healthy, if anything it looks more like potassium deficiency but mild since only lowest leaf is affected. I would lower the nitrogen, up the phosphor in your feeding schedule since she is flowering. If its a short flowering, no feeding at all to help her flush and she could be eating / flushing her own nutrients... If only two weeks of flowering left, this is a good thing. Just pick off yellow / wilted leafs.
