Welcome to week 4 of Flower!
They look so beautiful and healthy (in my humble opinion)
Blue Sunset Sherbert is the tallest by far with a lot of main even colas, cant wait to finish them
@PrinceBoateng, LST means Low Stress Training.
It's a training method where you bend the plant so the lower branches get more light, this will make the plant grow with an even canopy which makes you have multiple main buds instead of just one. :D
