korsitoanswered grow question 6 years ago hi friend, in the first images it is clear that you have a deficiency of sulfur, because of the yellowish color and its decay, being in advanced weeks of flowering you must place a greater amount of nutrients, I feel that you are placing very little, increase the dose , I do not think it is the ph since biobizz with its products is regulating it, I would advise 2 irrigations per week with nutrients. A greeting
