those pics were taken around day 45,
they were close to harvest time, i see a little boost in cola;s from plucking the big fan leaves a few weeks before its ready
mostly i will take the biggest fan leafs and twist them together (tie) them out of the way before i chop them off, or twist them so they are side ways and not flat to allow for more light or bend them away

honestly, ive done both and i dont see any difference
there may be more pics showing this in my photo albums

you can also take your finger nail and penetrate the stem before an internode, itll beef up your buds, kinda a LST/supercrop technique's, with a high bloom food like MOAB
