Nice job man,
I also am three weeks into my first top and LST with my 4 outdoor plants.
I have grown outdoor b4 but never topped or trained them and grew amazing , dank, single cola plants..
Now , like you I have 9-12 tops on by big girls and 6-7 on my smaller ladies. They are bushy as hell , although I have done a fair share of Cropping , because I like a mushroom look on top, but that's me.
Also I was going to untie her once she began to show female charc, but decided to leave them tied down....
I feel like each grow is just more practice for my next one.....
