When in flower to defoliate and / or popsicle?

I clean things up as needed. There is a cause to the effect of pruning. If congested or overlapping and causing standing water (condensation from touching leaves), that's a good reason to remove something.. but always keep the fullness of your canopy... wasted light missing the plant is the worst thing you can do at a this point. the products of photosynthesis are highly mobile within the plant. The plant will favor areas with greater apical dominance regardless of removing leaves here or there. i've heard this nonsense for so long.. i purposefully have a fan leave fully covering a budsite and after 5 weeks of flower, it has made no difference relative to other comparable bud sites at the same vertical height and similar vascular tissue leading to it (thickness of stem .. a 'primary" branch compared to a "primary" branch etc by "primary" i mean both orginate from apical meristem, this may or may not be the right technical term) Zero diffference from bright light hitting similar flower sites vs a 95% covered up bud site of equal potential given the above dynamics that actually are part of the causality of its development. So, defoliate is bad.. Selectively pruning leaves and growth tips that improve airflow and reduce probability of disease and other problems is good. Have a good reason to remove stuff. lollipoppin - if not extreme can have some merits. Again, the total yield of the plant will be roughly the same in any common sense context -- i.e. not taking off too much. What this "technique" will do is simply help you get less proportional larfy buds. Remember you can remove a growth tip but leave the fan leaves behind, too. If they are not a problem, leaves are value-added even if not in direct light. if they are a net-negative, the plant will shed them and that becomes apparent in a few days - they'll fall off on their own once the plant sucks them down. the main factor for yield is your photosynthetic potential. So the area of you canopy and catching all that light is the first and foremost priority. Any "technique" that reduces the photosynthetic potential of the plant will hurt your yield, no ifs ands or buts... Genetics will matter as far as how deep the plant will produce good buds. Some don't get larfy 2 feet deep and fairly well-shielded from light. Some get larfy quickly the deeper you go. So, familiarity with your typical results are the best guide for lollipopping the plant (pruning off lower, weaker growth in hopes the plant puts that energy elsewhere). Less is more as far as our behavior and actions. Don't overthinkg it or put too much value in what you do... the plant does 95% of the work. the plant's genetics are the ceiling for its potential.. not whether you ice the roots or do an extreme defoliation. (don't ice roots, lol). if you find good buds 18" deep, you should attemptm to lollipop to get an 18" deep canopy... this takes a little imagination... visualize how much growth is remaining early on in flower phase... this depends a lot on the plant itself... some streatch 2x some stretch 3x after flip. do your best and don't do too much... can adjust what you do as you gain more experience.

Puedes hacer la primera defoliacion antes de cambiar el fotoperiodo y una segunda defoliacion en la semana 3 de floración.
