Fare warning... If it's like my gelato it will stretch double it's size so keep that in mind. I had to do a emergency topping mid way through the stretch to keep it from touch the lights.
I leave the ties on and will continue to adjust them as the plant stretches during the first 2-3 weeks after flipping the light cycle. I adjust them so the canopy stays as even as possible. If a branch stretches too much above the others, I sometimes do super-cropping to help slow down growth on that branch.
