Supercrop or clone for sog?

I got some Moby Dick autoflower that turned out is not an autoflower. Its been about 80 days and no bud sites at all. I feel that it might be too big for my 2x2x4.5 so should I supercrop it, or just take clones and have a 6 sog grow? It's in some crappy soil right now and no nutes except fish and kelp, so cloning and sog would allow me to replant to FFOF and a good nute lineup. If I supercrop it would allow for a big plant, but I'm not sure if the space allows. Thank!

Yeah, she'll fill in that whole space by herself, done right. Assuming she gets healthier than she looks now. Why so yellow? You must get that fixed before going to flower.
What is up with those dead looking plants in the foreground?

I was being a cheap bastard and used some crappy organic soil with water only, that's why that aren't as healthy as they should be. If I clone and do a sog, I'm going to do it right and get ffof and good nutes. If I supercrop I'll just get proper nutes.

The plant in front is purple lemonade that is about to finish and looks better in person than the pics.
