I think it's just the genetics making it grow different I have the same as well and I can say that training Titan F1s isn't easy because of the structure being so dense and the nodes being so close to each other, it's an extremely bushy plant when I compare it with 🍎fritter auto which has an extremely open structure in comparison.
ps I do like the Titan F1 it's just not going to be a favourite of mine when it comes to training at least, and good luck with the rest of your grow 🤞🏻🍀❤️
