Strawberry Cough 4x4 Indoor, 480w LED

I defoliated 3 times total during flowering, I was afraid on the last one at week 5 but they were too dense again and the lower buds and leaves were showing light green coloring and no resin. This was the last defoliation and they have stopped growing new leaves, still plenty of them. At the beginning of the week I switched to Canna Coco AB ( my starter line years ago ), because I remembered the smell was very strong with it. At the end of week five, they started producing resing and smelling very strong and sweet. Yet, they were still showing red stems, so I added up more PK to the mix and voila, the smell exploded. and I relized at this point, how I had fucked up in the last grow. 1000-1100 ppms in, about 600 going out after the switch in nutes.
