Mainline = just one set of nodes which = 2 main branches. Both branches trained horizontally for a bit and then let go vertical. Usually topped twice in veg to get 8 main colas.
Quadline = 2 sets of nodes and 4 main branches. Fluxed-ish in veg and untied after stretch. Plants end up taller than a flux because they aren't fully pinned down horizontal.
Fluxing = Mainlining the plant and keeping it tied the whole way. The main support branches are tied down horizontally super early and everything is pretty much stripped the whole way except the very ends of the branches.
From LA's fluxing guide.
Final look
I think you pretty much ended up doing a half flux. Full fluxing is great but it takes FOREVER to do. Plus you keep them pinned down hard the whole way. Not that it matters and I'm not trying to correct you but rather enter my 2 cents on the subject. That's why I've always said quadlining is like a hybrid of fluxing and 4-way LST. When I was researching how to train plants a few years back I really wanted to full flux but I couldn't believe how long it took people in veg to do it. I wasn't going to veg for 3-4 months, that's way too long.
That girl looks great! Looks like some of the largest trunks I've seen you have at this point in a grow too. That is likely from your dialed in feedings. You'll have the biggest colas you've ever had on a plant unless something goes wrong.

Thanks!! 
...I’d get in the tent and go Edward scissor hands on them!
this whole thread is soooooo me.
