Default removing the fan leaves
So they question up for debate is if cutting off the fan leaves, or at least the larger ones!

I've heard leaves directly relate to the buds, more leaves/vegatation the better the nugs

I currently remove the leaves that get close to the size of my palm or hand. I feel as though the huge leaves take more of the nutrients and energy that the plant could use to grow, new growth.

I found too where i did remove the large fan leaves that the new branch above the leaf grew much faster and better

so i was wondering what other's experiences were, should i leaqve the leaves alone?keep doin what i'm doin, or least likely take more off?

thanks,

if you must remove some leafs then only take the ones with the purple stems, and only about 5% of them. good luck

Pruning/leafing

Leafing is one of the most misunderstood techniques.. 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. Possibly, 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 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. They 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 chlorotie (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. Your ladies 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 may 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 probably 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 probably not grow any larger. Leaf removal may also cause sex reversal resulting from a metabolic change.
If leaves must be removed, the petiole is cut so that at least an inch remains attached to the stalk. Weaknesses in the limb axis at the node result if the leaves are pulled off at the abscission layer while they are still green. Care is taken to see that the shriveling petiole does not invite fungus attack.
It should be remembered that, regardless of strain or environmental conditions, the plant strives to reproduce, and reproduction is favored by early maturation. This produces a situation where plants are trying to mature and reproduce as fast as possible. Although the purpose of leafing is to speed maturation, disturbing the natural progressive growth of a plant probably interferes with its rapid development.
Your plants grow largest when provided with plentiful nutrients, sunlight, and water and left alone to grow and mature naturally. It must be remembered that any alteration of the natural life cycle will affect productivity. Imaginative combinations and adaptations of propagation techniques exist, based on specific situations of cultivation. Logical choices are made to direct the natural growth cycle to favor the timely maturation of those products sought by the cultivator, without sacrificing seed or clone production.

after reading this article in the grow FAQ i would not cut any fan leaves as the plant falls back on stored properties later in flower

I am not a fan or advocate of removing plant matter, but i do prune 1 time at about a week or so into flowering,basically after the stretch is done. I take all the lower undergrowth that will not get much light for clones and create circulation. after that I remove nothing.however when ever pruning I take as little leaf matter as possible the leafs are what collect that light we spend so much time and money to provide them. also by pruning the way I do there is only a top canopy and no lower growth to worry about fan leaves blocking. and In my experience, the bigger the fan leaves the biger the buds.

I have said the same thing very many times but yet for some inexplicable reason many people still want and need to believe otherwise.

The information above is spot on and it should be accepted and followed by anyone who grows their own if they want the best results.

More people need to understand that expert advice is just that, expert advice and people's personal opinions are at best worthless and at worst dangerous.

Why do you trim new growth?

As a plant increases the number of leaves it has it increases the amount of light ray energy it can absorb which equates to increased growth and production. You receive an exponential growth rate which means a stage of rapid growth where cells multiply exponentially.

So by trimming new growth you inhibit the otherwise achievable growth rate.

So why trim new growth?
