Picture one i would say yes!Picture two i would go for the ones below the one you have pointed at because that one is getting light and is thin,the ones below it (on the stem to the left) get no light and are lower,which means there is already less light penetration and they are stopping it from reaching (if you have there) the budsites below!
If you want to be sure,figure out which ones are stopping the light and take a fan off each node!Check up Green's LEC grow for a detailed view of how he did it,but be warned,i wouldn't go THAT far right now!
