Hey,
I've seen and also had great success with breaking apical on autos...but only on the strongest most resilient healthy plants. Also if you can check their estimated growth time...the longer ones will have better success. If the growth period is too short there may not be enough recovery time. But I think it's definitely worth experimenting, if you can can afford to lose a plant once in a while(in case it doesn't work.)
But definitely the #1 factor in if it works or not...is the health and vigor of the plant.
Happy training.✌️
If they're are growing healthy and strong and in a big enough pot with a well known stable stain, its definitely not a problem, I've played with autos with great success! 🌱👍
