Defoliation week 3 of flower.

No, in my opinion. don't touch it. Each and every leaf is providing the energy for your plant to grow. Removing healthy green leaves just reduces your plants capacity to produce energy, slowing growth. Leaves also provide a ready store of vital growth elements such as sugars, carbs, amino acids etc that your plant will draw upon during flowering. It is far more efficient for your plant to re-use these "stored in the leaves" reserves of vital growth elements than it is to manufacture them from new during flowering. So, not only does the removal of healthy green leaves reduce your plants capacity to produce energy, it also robs her of vital growth elements she needs to grow her biggest and best flowers. This is why leaves will go yellow on well fed and healthy plants during flowering, the re-use of the stored elements she has in her leaves. Leaf removal will require new energy be spent on replacing the lost, previously stored elements, energy that can then not be used for flower production. Try only removing yellow leaves, for by the time they are yellow, they have served their purpose. Further, plants can not "channel" energy anywhere, all energy is used throughout the entire plant. "Channelling" energy would require a brain or conscious decision making. Clearly, plants do not have brains. The deranged idea that by removing leaves will somehow force a plant to "channel" energy to "bud sites" is dumb. Those "bud sites" are relying on those very leaves to photosynthesise and produce the energy required for growth. Plants will grow their fastest and best if all green leaves are left on the plant producing maximum energy for maximum growth. Fewer healthy green leaves = less energy produced = less reserves of vital growth elements = slower/smaller growth. It is plant biology 101. Cannabis has evolved over Millenia to grow her best and biggest flowers. Getting rid of perfectly healthy green leaves is not part of this evolutionary process. If cannabis would grow better and bigger by losing perfectly healthy leaves, she would have evolved to do so. As she has not evolved to getting rid of energy producing healthy green leaves for no reason, I see that there is absolutely no benefit to removing healthy green leaves, but I do see a lot of negatives and handicapping resulting from removing healthy green leaves that are producing the energy that your plant needs to grow her biggest and best flowers. Over 35+ years of growing cannabis, I have never seen a healthy plant ever getting rid of healthy green leaves for no apparent reason or benefit. I advise to leave all healthy green leaves well alone to do their job of producing energy that your plant needs for optimal growth. People worry about stupid things like "fan leaves are shading "bud sites", so lets get rid of fan leaves, that will make the "bud sites grow more". This is utter nonsense, those "bud sites" need those fan leaves to produce the energy required to grow those "bud sites". Plus, after 3-6 days, those bud sites will grow from underneath the fan leaves anyhow, making the removal of the fan leaves pointless. On top of all this, those tiny small leaflets associated with the flowers can in no way produce as much energy as just one healthy green fan leaf. Less leaves = less energy = less growth. It is that simple. Sorry, de-leafing as a principle rubs me the wrong way and I tend to get carried away explaining why it is such an outdated and bad idea. Your plant does need every healthy green leaf to produce energy so that she can grow her fastest and best. Less leaves = less energy produced = less/smaller/slower growth. Here endeth the sermon of Organoman. I hope it helps in some way.
