I agree with everything you’re saying except for the flush. If the plant is being fed non organics, it needs to be flushed imo. I’ve tested both ways, when I do a proper flush the final product burns way better than without flush. I live in a place famous for cannabis production, and I’ve been privileged to learn from a ton of professional growers. Every commercial grower has a different method / ideology regarding flushing, but they all flush their plants.
