I grew 3 autos really well outdoors in 1 part worm castings, 1 part perlite, 1 part coco, 1 part vermiculite using flora nova nutes (basic feeding schedule) at full strength starting from week 2, they all yellowed in good timing with the trichs, harvest was about 2-3 weeks later giving plain tap water for the last 2 weeks. It was a really simple grow and nice yield, 4 oz off 3 plants.
