Yup - what DT said. Maybe try a little LST to spread the plants out a bit for better lighting (ie bend one plant about 45 dgrees to the left and the other to the right) Make the bends as low as possible and it should redirect growth in that direction.3 months? those should be some pretty decent plants about ready for flower, no? im almost 100% positive the 2 plants roots have merged into one huge root ball. and separating them might kill them. id leave them if it were me, and pot them in a 5 gallon or larger pot if you have room. one you repot them, you should see the enormous intertwined root ball.
