They look really nice.
That is a tall strain that will stretch a lot. Yours are still small so you still have control over their growth. Give up more time for more yield. Take the smallest of risks and get more yield.
It can only grow so tall before you have to flip or risk it getting too tall after stretch. With a stretchy strain you should TOP your plants. This is easy, 99% successful for a newbie who is careful. That will add a week potentially to the veg time and will give you 2 tops per plant and more side branches.... more yield.
If you wait for several new nodes to form on each, you can top again for 4 mains each. This will add up to another week, but in return will give you a much higher yield and more branching. Some LST such as tying down the mains a bit can give you a broader table like base. Another easy although stressful step for a new grower.
With a small number of plants, some training and topping is a great option. At a minimum you would increase potential yield by 2x if you top them twice.
The best news is they are already established and if you top them they will recover super fast, potentially with no delay.
If you have say 7 feet of vertical space and 2 feet is taken by lights and pots, you have 60" left. The plants can be 20" tall and still stretch to 3x original size and fit your space.
Thats how I would do it...but thats me and why this is fun. You can flip tonight and be happy too!
