-hahahahahaha this thread is hilarious. Also, you may want to consider your options a little more carefully than just topping because it looks like its the right size. do you know what kind of plant it is, or know someone who has grown the same variety before? some strains respond very well to topping, and you can top twice and get 4 huge colas. Some strains, however, do not respond well at all, and you could end up with a couple skinny colas that would not equal the size/weight of what you would have had if you had just left it alone.
-My advice is, unless you know that topping will be beneficial, leave it alone... just a little pruning of the bottom leaves so the plant can concentrate all its energies on the upper buds and top cola. you'll wind up with bigger buds if you prune right, but like I said before, make sure u know what you are growing or at least know someone who can tell you how it will respond to what essentially amounts to surgical amputation for plants. especially if you only have the one plant, you wouldnt want to ruin it, especially when theres already a 50% chance it will go male.
