You don't have much control over the autos. For the photos, it's just room, light, and nutrients. You need room in the container for a large root mass, so up-pot in stages to a ten gallon or larger container. You need room for a larger plant, at least 6 sq ft (0.6m^2) per plant, and a longer time in veg to grow into it. You need plenty of light, about 900ppfd or 60,000 Lux with a good spectrum - for your entire canopy. You need to provide an appropriate amount of nutrients and water to support the plant through its various stages of growth. All of this, and decent genetics will let you grow plants indoors that yield 8 or more ounces when dried and cured.
In my 2' X 4' tent the most I've harvested was close to 8oz under lights that didn't meet these criteria. My first harvest was 5.2oz. I'm looking for more from my next harvest when I have all the pieces in place. It will have taken me three years to get there. Don't give up on your vision, just soldier on and improve your knowledge and growing conditions until you achieve your goal.
