Small , regular adjustments is the way to go for sure, looks perfect so far just keep doing what you're doing, yield is all about veg, more veg, bigger plant, bigger plant more yield. Folks do understand that internet culture makes folks try to go fast with 4 week veg, but really an average veg time is 7-8 weeks. if you go that long you can easily break the 120g mark keep bringing the LST cola down away from the light. right now you're going quite extreme, at some point you can release it a bit and it will do better towards flowering . Hope this helps ! 🚀
