the problem with autos is that they stiffen up really quickly. People say you can always LST? well, not with autos you can't. Dont be disappointed though , any kind of LST at this point will actually impact your yield in a negative way. if you LST too late the flower nodes dont grow correctly and you have asymetric buds with some small buds due to the LST. What i can say is that you're doing really well right now , the bush shape is the desired shape, the many leaves are a good sign that the plant(s) will go through a great flower stretch. Dont panic dont feel bad. Next grow just start LST around week 2 and you will be fine. the point of LST is to promote lateral branching... you have plenty of that already, so that's good ! Hope this helps ! 🚀
