Hello dude, i'm no expert on growing. I have had two successful grows, i my mind, lol. I'm now on day 10 of my first attempt with autos. one northern lights, one gelato og. I did a lot of reading on autos before a started the grow, and the general consensus is, because autos grow so fast, they don't respond well to stress. the general recommendation for beginners like us, is, do not transplant, plant directly into the pot you intend to grow them in, do not top, you can do LST, and no nutes for the first 2 weeks, then start at 1/4 strength. yields from autos greatly vary, from as little as 1/2 oz to 6 oz, with the average being around 2oz. that's my goal! I planted mine directly in 3gal. pot, soil, 60% happy frog, 40% perlite. so far only water, ph 6.5. FYI, white vinegar works just as well as PH Down.
