My girl is 36 days in flower and she looking bad lol she is definitely certified on the frosty part lol anyways should I defoliate a little or just leave her alone Is the issue today. I hear a lot of controversy on the subject of doing it vs not. But if I do it will only be the fan leaves covering bud sites. But let me know how yall feel on the subject? 20180220_060813.jpg 20180220_060800.jpg

every leaf makes energy for every part of the plant including every leaf. They dont block production.

If you want less photosynthesis to take place=remove those engines.
If you think you need more light buy more light.

Defoilating or de-leafing is one of the most misunderstood techniques of drug Cannabis cultivation. In the mind of the cultivator,several reasons exist for removing leaves. Many feel that large shade leaves draw energy from the flowering plant, and therefore the flowering clusters will be smaller. It is felt that by removing the leaves, surplus energy will be available, and large floral clusters will be formed. Also, some feel that inhibitors of flowering, synthesized in the leaves during the long noninductive days of summer, may be stored in the older leaves that were formed during the noninductive photoperiod.


If these inhibitor-laden leaves are removed, the plant will proceed to flower, and maturation will be accelerated. Large leaves shade the inner portions of the plant, and small atrophied floral clusters may begin to develop if they receive more light.
In actuality, few if any of the theories behind defoilatin or de-leafing give any indication of validity. Indeed, leafing possibly serves to defeat its original purpose. Large leaves have a definite function in the growth and development of Cannabis. Large leaves serve as photosynthetic factories for the production of sugars and other necessary growth sub-stances. They also create shade, but at the same time they are collecting valuable solar energy and producing foods that will be used during the floral development of the plant.

Premature removal of leaves may cause stunting, because the potential for photosynthesis is reduced. As these leaves age and lose their ability to carry on photo-synthesis they turn chloro tie (yellow) and fall to the ground. In humid areas care is taken to remove the yellow or brown leaves, because they might invite attack by fungus.

During chlorosis the plant breaks down substances, such as chlorophylls, and translocates the molecular components to a new growing part of the plant, such as the flowers. Most Cannabis plants begin to lose their larger leaves when they enter the flowering stage, and this trend continues until senescence. It is more efficient for the plant to reuse the energy and various molecular components of existing chlorophyll than to synthesize new chlorophyll at the time of flowering. During flowering this energy is needed to form floral clusters and ripen seeds.

Removing large amounts of leaves will interfere with the metabolic balance of the plant. If this metabolic change occurs too late in the season it could interfere with floral development and delay maturation. If any floral inhibitors are removed, the intended effect of accelerating flowering will be counteracted by metabolic upset in the plant.

Removal of shade leaves does facilitate more light reaching the center of the plant, but if there is not enough food energy produced in the leaves, the small internal floral clusters will not grow any larger. Leaf removal
may also cause sex reversal resulting from a metabolic change.

Canopy looks awesome, i wouldn't remove any more than what you may have already. upper leaves are built by the plant to handle acquiring the maximum amount of photons, but they cannot capture them all. some photons go right through the leaf (light funneling through the palisade mesophyll) and then get captured by shade leaves, which are below the sun leaves in the upper canopy. @vostok has a great reference there, and I would definitely use it compared to a lot of the "bro science" that circulates the internet. and leaves attached at a certain node doesn't necessarily feed the bud site at that particular node, it may be feeding a different bud site on the shoot. and like Clarke mentions, if the leaf can not generate the same amount of food energy as the one removed, you're not going to see an increase in bud size. those upper sun leaves capture far more energy than the thinner shade leaves below. I mean... we can go down this rabbithole even farther but I think you see the gist of it.

one benefit from removing leaves from plants that have a high leaf amount in the canopy is that it increases airflow, and reduces the chance for mildew forming between leaves that settle on top of one another. I don't think your canopy needs any defoliation for this purpose. Looks open and clean.

let her rip!
