If you are not taking any cuts off these, take the top off at 7, leaving 6 nodes beneath. Remove both branches from the bottom leaving 4 nodes of branches on each plant. If you can get that done on all of them cut them all at the same time and flip that day. If you need to wait on a few, just wait on do it when you can.
Many will top and flip a week later which I have never understood. The whole point is to create a smaller plant with more tops which benefits LED growing so plan to cut and flip.
You’re hydro and it’s go time!
If you find you have a plant that needs to be saved, I’ll show you how to reveg in 14 days and we’ll take cuts.
