If you're possibly 4 weeks into bloom then bending is probably your only option, or at least the best one. I wouldn't cut it at that late stage.
Once you get set up with the bend, concentrate your lights on the top part of the plant when the plant gets to the point where there isn't sufficient light to cover it all - assumming it does of course. A 1000 watt will cover 5 feet so put it about 2-1/2 feet from the top end of the plant. (I'm not talking about 2-1/2 feet above it, but rather 2-1/2 from the top end, know what I mean?) Add your T5 2-1/2 feet down from that. I made a quick picture to help explain. (Yeah, it's a horrible pic but I didn't want to spend a lot of time on it, you know, besides that, I'm a terrible artist.)
I'll see if I can find some easy to understand info on bending for you but I can't do it at the moment ... I'm already running late ...
I think you can make this work. If done correctly you should even be able to get a decent yield out of it. Sounds like you're going to have to learn some things about nutes and watering etc. but let's try and save this thing first. There are lots of people that I'm sure will chime in to help with their own ideas here. Could be someone even has a better one ... this is all I can think of. Oh yeah, I'm not sure how you are for ventilation but your 1000w light can go as close as 1 foot above the plant IF you have amazing ventilation. For now, and especially since the plant is going to be stressed, I'd put it no closer than 2 feet. The T5s, you be the judge, but don't be getting that plant overheated.
Hmmm ... I'm not sure where that square at the bottom of the pic came from but it means nothing. Let's call it a ballast. LOL
