You could try bending to force the plant horizontal altho don' get too aggressive with it or you could stress your plant out, otherwise good job shes a monster!
Bend 'em over, do it just before your next watering, tie them down with string. It's obv from the pics you don't have enough light.

if u dont want to LST, which i think u should IMO for 2 reasons (u will get more light to the lower brancehes thus increasing your yield AND keep it at a manageable height if height is a concern)
