Please don't feel as if you fucked up! There are manifold ways of doing manifold. (pun intended, lol) You are correct for your understanding of the process and you will go on to a bountiful harvest of large colas with maybe a few smaller buds. I'm of the school which says the more buds the merrier even if some lower ones are smaller, they all smoke very well and the debate over which is better will rage on and on. Very large colas or many many buds, the final yield is more than likely a moot point. There are way to many factors that influence final yield to stress over just one. Your doing a fine job of on the job training, no worries!
