Too tall

yes, shop it! dont overthink it..she will make for it, the whole plant (and buds)gets more light then too, good luck

You could just chop the roof off your tent and grow until you hit the ceiling. Duh

"snap" it -- really you want to slightly damage a point on the stem and bend it over... support it for the first 24-48hours then after that you probably need to tie it down to prevent it from self-correcting. the tip will grow vertically from that point, so tie it down near the end of the branch. Consider this when you choose where to break it down. it'll heal within 24-48 hours. The knuckle that forms will be even stronger than before. If you see wilted leaves for more than 24h, be a bit gentler next time. You can do it with zero wilt, too. It's something you need to get the feel for.

If you have your ventilation above your lights get it outside of the tent somehow and get the light up as high as you can and dim it some if you need to, chopping top colas should be very last option they are looking good. you could always try to supercrop before completely chopping them. You fan and filter can be on the ground next to the tent as long as you hook the tube to the top of the tent the fan will still draw all the hot air out.

No the tent is just too short =p
