Your a little tall and stiff to LST the main stem AT soil level I think. However you look to have a lot of extra stick down there too.

I'd suggest re potting. Although you answered the container size question with nothing but a question mark.:wtf: It also looks to be a sizable pot, but pics are deceiving. When/IF you repot, you can trim off those lower leaves and bury the plant deep, thus burying nodes that have no leaves. All that excess stem will grow roots once buried. Plus it'll be easier to bend what is left above the soil.

Once you have all that excess stem in the dirt, start bending little by little to expose side shoots to light. In turn they will grow into branches to tie back. Then undergrowth on the branches will grow into more branches to tie back. Once the plants top reaches the edge of the pot, start tying it around the pot.

It'll grow to look like this,..
