That's a good question. During veg, I just use ph down, ONE veg growth premixture, and a drop of Super Thrive. When I get to flowering it gets more involved scheduling different solutions. I use Bat Guano, Boost, Big Bud, A premixed flowering solution, Bud Candy, and Humbolt Honey. THESE ARE NOT USED ALL AT ONCE EACH WATERING TIME.
The funny part for me is I have a good friend that grows outdoors and get decent stuff - What does he use? Water straight from the garden hose. and during flowering a can of Dr. Pepper. I always wonder if all the stuff I use is overkill, but I do come out with great tasting and powerful medicine. His is okay, but he drinks everyday and take pills so he always thinks his stuff is the best. lol
