How this is done

Yo guys, thanks all for replying back. Closest to answer was @Justa_Retard, but still didn't found the right answer. I didn't say here leafs fell of by them selves. Yes he may be cutting till now. Question is simple: How do you make them become like that?

You're jumping to the wrong conclussions, @Milf420 This plant have been heavily defoliated.. Everything below the top buds on each branch, have been cut off. If you zoom, you can easily see it. - It didn't happen because the leaves fell off by themselves after turning yellow, it happened because the grower made a decision that they weren't needed. What you call waste, promotes bigger buds on the top of the plant, rather than smaller buds all over the plant.

Hi, It seems your plant the final stages of its life cycle. You might stop feeding the plant and just give it water. Look for cloudy crystals and pistils turning Orange or red then you can harvest. Happy harvest!!

The removal of a particular leaves will improve growth, plant health and yield. A lot of wins. Not removing leaves will grow giant leaves, create air circulation problems and uneven growth.. Nutrients available to the plant will not be wasted by defoliation.

Seems everyone just cuts the leaves to make space for more light, but what they do is waste all those precious nutrients in it! I have seen lot of images online similar to this, and no its not nutrient lock downs or any other issue with the plant.
