No, no.
By all means - leave the budding sites - but snip off all the fan leaves that attach themselves to the stems/branches and aren't themselves directly attached to a flower - these should be the largest fan leaves that are blocking light to the lower flowers.
Even with mounting a big t5 along the bushes, you'll still be leaving *alot* of yield on the table if you leave the plant completely unmanicured. Canopy penetration is really important if you want anything other than the tops to flower . . .
I know it seems counter productive to snip so many leaves you watched grow, but you need to do it . . . there has to be a good guide here somewhere . . . anyone?
lurch said:why would you ever want to trim fans off if theyre healthy?
lurch said:where do you think the plants convert light to food 4 ur "flowers"? if
lurch said:so if you have done this what would be a percentage of fans that youve taken
lurch said:i do take fans but never in flower. IMHO you will lose yield
scrapion said:Pulling healthy leaves off is a no no.
By the 4th week of flowering, the OP should have long since trimmed his plants.
I generally trim the last week of veg - sometimes before if there is something I want to rearrange. Eitherway, trimming fan leaves now won't hurt him, and should increase his yield a bit from the rather brief description he provides of his grow situation.
lurch said:in flower no i dont believe in cutting any healthy fans, just tuck em outta the way. have a plan laid out b4 comitting to flipping to 12/12. like you said in veg yes do pruning/training.
lurch said:you dont think clipping about 1/2 way through flower will stress her out & slow down bud growth? i do.
sedate said:if you think a fan leaf blocking a budding site 12 inches lower on the plant will turn the light it recieves into energy for that budding site, then you have a seriously flawed understanding of plant function.
The large fan leaves left over from the end of the veg stage are doing nothing for the size of the flowers - they are keeping themselves alive and absorbing light that could be better spent producing actual smoke.
Phloem moves from sources (areas of supply) to sinks (areas of metabolism or storage). Granted that the flowers can produce some photosynthate, but they are no where near as effective as fan leaves (resin glands significantly reduce light to the tissue they are found on). Flowers are sink tissues, leaves are source tissues. Sinks do not produce enough photosynthate, and are importers. Sources give photosynthate to sinks in closest proximity.
...
During flowering and fruiting, only the very bottom leaves supply the roots and the rest of the leaves try to get as much energy as possible to the flowers of fruits. For this reason, the more leaves are unshaded and in good light, the more chance the plant has of creating extra storage of energy that will ultimately go into yield (Leaf, 03.13.2002).
sedate said:You seem to be thinking that cutting of a fan leaf is like cutting off a finger - it's not, it's more like cutting hair.
Removal of fan leaves will not only slow growth, but it will also hinder the plants ability to rid itself of toxic gases, and also hinder the regulation of the plants temperature via stomata. Changes in the plants chemical metabolism caused by fan leave removal causes the plant to work overtime to rid ‘toxins’ with less leaves, as a result the pant may allocate more growth hormones into growing more leaves to make up for what has been lost(Equator, 03.15.2002). Removing large amounts of fan leaves may also interfere with the metabolic balance of the plant. Leaf removal may also cause sex reversal resulting from a metabolic imbalance.

However Jeast (03.13.02) believes that the rich green leaves emerging from the bud are a sufficient energy source of solar energy for the plant's floral development. Therefore the old fan leaves are once again rendered useless and only drain energy from the developing part of the plant (Jeast, 03.13.02).
post up some pics first so that I can point out where... its just like topping it, expect taking more off. At my buddys house he had some ROG seeds I gave hime that streched like a mofo, (to his own fault) I told him the same thing and now 2 weeks later you can bearly tell he cut that much off. They dont say it grows like weed for no reason.
