Master Kush 2 mos into veg as mother want to clone

OK, I started from seed and now my Master Kush plant is into week 8 under veg. grow, I FIM the plant earlier, then because the bottom leaves wasn't getting enough light due to only using fluorescent 6500k 40w in veg room, I tried LST method.So now I was wondering if I could cut all the main stems and use them for clones, the two that branched off at the top, and also some of the lower ones. Keeping one or two at the bottom to try and continue the grow. Any advice or suggestion will be appreciated....I have been using FF nutes only for the Veg stage since I was planning on this being a mother plant, it growing in a 5 gl container using pro max soil.

Well here's an update on my cloning attempt. After taking the cutting's (4) I used Olivia Cloning Gel and dipped each cutting in the gel before placing in the Rapid Rooter Plugs which I soaked in a regular tap water solution ph'd at around 5.5 and placed in a Burpee Cloning tray that I had laying around, the round plugs fit in the square sections quite well. I also placed the Burpee tray inside a Jiffy cloning tray with some perlite on the bottom and poured water in the bottom of the tray to help with the humidity in side the dome. After checking since the 19th of December for any new root growth, I discovered today after cutting the plugs open, root development. I carefully removed each cutting from the remaining plugs and placed them in my Bubble Cloner to help speed up the root growth. Sorry the Pictures didn't turn out that well.
