Hey. So I see your plant has more leaves and small node growth
There's a few thing u can do here.
See those 1 fingered leafs. These can can be removed with the nodes (growths) tat sit above them. As the uppersets have 3 fingered leafs will outperform these low nodes and outshadow these throughout the the plants growth
Also to promote node growth you can bend ur plant on a slight angel / making more light to hit the leafs that transfer their energy into making nodes that will be able to sustain themselves when the fan leaves have done their job.
All about energy management. Doing things like this will speed up veg ad opposed to waiting for rhe natural time. As leds/lights are static lights. Unlike the sun doing a 180 around your plants practically covering points with static lights u need to manually move drive leafs nodes by managing energy correctly and as efficiently as u can
