Maybe we are at cross purposes....you said a few weeks away right? Now is the time that you should be seeing the buds fill in....both with more pistils and the three down to one fingered leaves. So are we talking about the same thing or are you talking about 5-7 fingered fan leaves growing more and more and blocking the light? If it isn't fan leaves then no, don't trim. I'd think the bud leaves WOULD be immature at this point....they're just starting to grow but I may have missed your point.
