Northern lights? Mseeds.nl

Hey guys, I ordered some Northern lights from mseeds.nl last July they came Germed and grew, no problems, but they are huge. I only vegged one week before 12/12. They switched around day 7 ( august 7th) from germ. Fimmed as soon as they had 2 sets of leaves tryna keep em short however here I am today with plants between 5-7 feet tall ( bout second week of showing flowers) bent and tied everywhere I have taken up to defoliation ( I know a lot of people are against this but I'm desperate) tryna keep the canopy somewhat even and get light to all parts. Anyway I'm just looking for some help training and maybe someone that has grown these seeds before because I'm fairly certain there is a haze crossed in there but idk not a pro just a passion grower.
Thanks for any help

Oh yea it's grown under 600 hps in a 3.5x3.5 flood table full of lava rock, gh 3 part nutes supplemented with nectar of the gods line.
