Carmen,
You'll need to pay attention to when the autos sprout as they usually start to flower around 3-4 weeks of age. I sprout them in solo cups and leave them there until the first signs of flower. When they have their second set of true leaves, I start feeding a low dose of nutrients (I am not organic) and increase it slightly until they have 3 sets of true leaves. Once they start showing signs of flower, I top as high as I can and transplant into a 3 gallon pot. I will start LST once the top two budsites have grown enough to pull down with pipe cleaners. Once the lower nodes have caught up with the top two colas I release them from the pipe clears and just let the plant grow. Hopefully that all makes sense.
