So I've seen some very good growth this week. The little one who is two weeks younger is just about caught up to the first. She will probably get topped some time next week.
For picture 1
You can let the 2 tops branches grow 4 nodes
Top the 4th node , take of leaves and branches on the 2sd node , and let node 1 and 3
Node 1 and 3 will grow 2 side branches each , the plant will finish with 8 main buds
