Just top it man, it might be real bushy already but if you top it, for the most part, what you loose in height you gain in bushyness! So your neighbors wont see it and youll still have a lot of bud! Bending sounds like a good idea too but I'd be scared to bend mine just in case the stem snapped.

And as for when it starts flowering, typically plants are supposed to flower when they recieve 12 hours of light or less. Not direct light, but light in general. So while it may only be recieving 4 hours of direct light it is probably getting a good amount of other light throughout the day which is why it is still getting bigger and not exactly flowering like crazy. Even once it does start flowering a lot though, its still going to grow upward more; you truly have a monster on your hands! Also, it probably won't be ready to harvest until late october which means it will be even huger!
