This may be a dumb question but i have 4 plants 3 days into flowering and was wondering what would happen if i pruned all the fan leaves off? Please dont be hostile its only a question.

The plant my produce slower because of lack of food making leafs they will die back naturaly as it flowers

it will stop growing and have no way of absorbing the light it needs for photo synthesis/.....

The final harvest would be effected drasticly these act like mini sola panels and give the plant more reflective light.There is only one time to prune and that is when the leaves are bright yellow near the end of the harvest.The only pruneing that i do is i take any lower brances out so there is none on the bottom stem for about 6 ince do this in the 2nd week of flowering.You could leave them on to make butter or hash but i can't be bothered with all that i want thick dence buds.I see no point in useing my nutrients on the bottom buds they produce very little.I also flower at 1 ft 1 and harf at most this gives optimon light for flowering.

Yep what she said he said
I do some fan leaf trimming when doing a heavy Lst, because it just gets too crowded some times, but it's better to bend those leaves down (like you do when super-cropping) and leaving as many as posible. Over pruning can stunt growth as well

yes leave them alone.
have a read at this thread.

not that this wasnt answered.. just thought i would try to explain it more...
fan leaves are produced to absorb light... light is absorbed by these during photosynthesis and is changed from light energy to chemical energy... this energy is what is used to power the chemical reactions that take place throughout the plant... imagine light is an alternator that recharges a battery that powers the plant... and that fan leaves are the medium by which the alternator gets power to the battery... the more fan leaves there are, the more energy that gets to the battery, the more power the battery can produce... power here meaning growth in the end... its somewhat of a sloppy comparison.. but its gets the point across..
you do not want to remove fan leaves... unless they are 50% or better damaged, or you are lollipopping your plant for flowering, you stand to gain nothing from removing them.. the plant actually will focus on regrowing them which means growth can slow down.. plus it causes stress.. although the amount would depend on the overall size of the plant and how many leaves were removed...

explain what more?? photosynthesis?? or the fact that the plant will waste energy trying to repair damaged leaves, so thats really the only time to trim them?? either way, here you go...
plants use light for photosynthesis... photosynthesis is the act absorbing light through leaves and changing light energy to chemical energy and storing it in the bonds of sugars... this happens in the chloroplast..
photosynthesis occurs mainly in the leaves, with little to non occuring anywhere else in the plant... and within the leaf the only place that chloroplast is contained is in the mesophyll... so thats the only place it occurs... the rest of the leaf contains structures to protect the leaf (upper and lower epidermis), stomates to breath through, and veins which carry water and nutes...
there are 2 parts to photosynthesis... the light reaction happens in the thylakoid membrane.. this is where the light energy is actually converted to chemical energy.. chlorophyll and other pigments that are located there assist in the actual process... the harvested energy is stored via a chemical called ATP, which is used by plants to store energy..
the next part doesnt need light to occur, but cant occur without what was produced during the light reaction... this is when co2 is converted into sugar using the product of the fore mentioned reaction...
the sugars are used for releasing oxygen, as food for the plant, and are used to cope with stresses... the more leaf surfaces, the more light can be absorbed, the more photosynthesis takes place, the more energy the plant has, ect ect.. this assumes co2 is plentiful.. but thats not the point here...
as far as damaged leaves...
slight damage to leaves will often be repaired by the plant... when we remove leaves, aside of reducing the amount of photosynthesis that could take place, we divert attention from the plant to mending or regrowing the removed leaves... when leaves are damaged beyond 50% it will take less energy for the plant to regrow them than it would to mend them.. if the damage is less than 50% you can choose to remove the damaged part by cutting it off... it will still take less energy to regrow the cut part than to fix the damaged section... but regrowing the entire leaf will take more effort...
typically it is best to allow foliage to drop naturally from your plants.. if the plant doesnt want the leaf it will drop it... but if you have overly damaged leaves, or if you are planning on lollipopping, it is acceptable to remove the foliage.. again, it is not recommended to remove and growth under most circumstances though..

Thanks again fellas i didnt mean for anyone to get hostile over a question but thanks for the info
