Lookin good my bro, cant wait to see how they go with the extra light.
As for the trimming its basically up to you if you want to trim more off or not. I usually like to have most of my trimming done before flowering but as the plant continues to grow during flower some branches dont take off as well as others so I remove them. Basically if the branch is only goin to produce little light buds then I get rid of it coz they are the suckers that I dont want. If your unsure then the best thing to do is trim some and leave some so you can see the difference with your own eyes and then you will know exactly what to do in the future. You will get to know which branches you should trim during the veg stage to save yourself from trimming during flower.
Fuck im wasted so I hope that all makes sense
