Normally I use 24/0 only during the seedling stage or when doing clones. I back off and actually use a 16/8 schedule during veg. Stretch occurs either with insufficient light as a seedling or at the point of transition to flower you will see a burst there. That can be reduced by a gradual reduction from veg time to flower time over a week or so. I also do this so I can better control my space.
You’ll figure it all out with your individual setup. Plus if you’re like most of us you’ll tinker with it to make it better too.
