Hey there Pablo, If you've recently flipped your lights , I would give them another week or at least make sure that the stretch is well and done with before stressing the plant with defoliation. defoliation seems like a nothing for us, but it's HST for the plant so it does get some sort of shock right? Still though, i would defoliate, not a lot though, really take out the most egregious fan leafs, those directly shading flower nodes. plants "feel" the light on those nodes and do send them more energy getting them buffer. Hope this helps ! ๐
