Overall pretty healthy, I wouldnt worry about pruning until you have some secondary to prune. Right now it would be more of a beheading of the cola and the few side branches growing out of the base of the plant. Let, it veg awile and produce something to prune first. Where you are growing outside,you aren't limited to space like most "kids" on this forum trying to grow in their closet without mom and dad finding out.
You are not limited outside, why go hacking otherwise bud beaing nodes off your plant?
Let it veg and when you feel the plant is starting to show pre- flowers. you might get under the plant there,and prune the brushy crap away, Pruning a plant and subsequently stoping and stunting the( bulk-up of this plant ) could be limiting it's production. left to grow this could produce 2, 3 who the hell knows how many ounces, Indica dom plants like this grow long whispy secondary banches,that in return grow more (terrciary ). They get large and bushy on there own. Prune to CONTROL size and prune for yeild when sighns of bloom start. Top if you want to create multiple colas, but let it get big,and bushy, by allowing it to grow to it's genetics potential first, It will get much,,,larger if you let it grow side branches (secondary) and terrciary growth before ya get to pruning.
