Mandarin Cookies V2R1- MurD edition

I would do low stress training and flip the light to start flowering. You can pull the branches apart a bit which will allow light to the leaves below and allow good room for the buds to develop. I like LST better than using a net because it allows you to remove the plant for inspection, training and pruning. It is much better to catch problems early. You can do some topping and try to create more budding sites but plan on adding 2-3 weeks before flipping to flower. Personally I think your tent will be feeling small when the plant stretches. It could get 1/3 to 1/2 bigger than it is now so plan for the future.
