Barneys Pineapple Express

This week did not go as I would of liked, 3 out of my 4 plants continued to show more yellowing with leaves falling off in different areas from top to bottom. I dimmed my lights another 5% to make it 30%. I flushed the problematic plants first using sledgehammer then waited a few hours and used straight water until the run off was between 300-400 PPM. On a positive note despite all of my shortcomings I am still seeing steady bud growth on each plant. As for the 4th plant, I fed it the same amount as the previous week and everything continued to go as planned. It packed on nice bud growth with hairs starting to turn orange. I have some minor yellowing at the bottom but nothing compared to the others. I am starting to notice a pleasant fruit smell in all my plants as well.
