Tropicana Cookies Auto FustBuds

On the 56th day, there seems to be a phosphorus deficiency again, judging by the appearance of the leaves. I pruned the affected leaves and started adding Advanced Nutrients' Overdrive to the water. Before that, I flushed the plant with pH 6.7 water until runoff. Overall, the buds are still gaining weight, but the foliage's condition has worsened. I'm considering starting the flushing process in about 2 weeks, followed by harvesting.
