Pretty damn lanky ...
IF AND WHEN this plant goes into flower it
will stretch even more .
My 2¢ .....
Look at diagram .... remove burned / necrotic leaf
LST mid and lower branches ( easily attached to pot ) - “ carefully “ anchor open.
Supercrop at this point to lay that upper sideways .... carefully pinch and fold.
NEXT add more TOP SOIL to that shallow amount you are using. Grab FFOF , no other Nutes necessary.... just top dress and water in. Let plant start to RESHAPE and get a more even canopy.
Supercropped area can also be tied ( LST ) as knuckle begins to heal. The main top will throw growth upwards from the side and make more tops.
Lastly add more light . CFL or something to ADD more .
