When your plant begins flowering which you are about 2 weeks into flower. Your plants food demands ramp up because the plant stretchable ND sets its structure and starts doing different chemical processes that use more potassium phosphorus calcium and and magnesium especially. At this stage you want be raising your P and K and lowering you N also you want to be adding calcium and magnesium often . You have a phosphorus and calcium deficiency in my opinion you need to feed more
