From my friends experience you can train the plant all at once without adverse affects. My friend recently bent her plants as described below.
Plant is roughly 7-9 nodes tall or about 2-3 inches when flowering began. Let the plant grow until the tip could hang over the rim of a 10 inch pot. Got a thin piece of nylon or whatever and gently tied her all the way down. Now we are talking a plant that is 2 inches tall and in full bloom. At about 8 weeks now and the buds just now are starting to dense up with about 50 percent of the hairs turning. Looking at more than an oz a plant of nothin but bud. Plan on harvesting in stages. Take ripe buds and let lower ones grow a week or so longer. Anyhow, not my first rodeo so not worried.
Monday mornin and I have to go in to work. Later
