Welcome BT. It mainly comes down to those big 3, we all just drive ourselves crazy trying to micro manage them...lol
I love that podcast but have to laugh at it some in hindsight. The Dyna guy tells you that all you really need is a complete fertilizer like Foliage Pro and Silica, and that you can run that start to finish. All the other bloom boosters and such are manufactured and sold just because people think they need it, and corporations are out to make money selling you shit you don't need. Yet when Dyna starts to officially market to the Canna crowd, what does their feed chart look like? A whole laundry list of products, just like every other nute company out there. A bit of hypocracy you think? Lol
