I have damaged a few cameras from trichomes.
I have found that packing the soil in the pots slows down root growth and cuts oxygen. I never pack the soil and allow the watering to pack it softly. When I move a pot, I don’t allow it to hit the ground hard, either. I set it down softly or lightly to avoid compacting the substrate. Before I pot up the soil it's as light as a feather before it gets any water.
I feed with a low ppm with every watering so as not to break the nutrient sequence. The plants take what they need and get adjusted to the EC. Since everything is there with every watering the plants find it easy to get what they need without having to search through a bunch of impurities. Only pure liquid feed.
And here I am, watering with plain tap water with pH 8.2. Reusing the same soil too. And I almost never water to runoff.It's truly the basic concept you stated. Continuous liquid feed.
