i have 4 plants 2 weeks into their flowering stage. i have been told that cutting off some of the fan leaves will allow more light to reach the lower flowers. does this work or do the fan leaves act as light catchers for nutrients? thanks alot

I wouldn't really recommend cutting large fan leaves from your plant. Yes They do catch light and convert to food, so if you look at it this way, you would be cutting a big food catcher so that a smaller food catcher could catch light.

The smaller leaf is obviously not going to be as efficient as the large leaf.

agree, imo i would only cut bad leaves.

However....

If, say at week 6 you have a large fan leaf that is yellow and soon to die off from lack of Nitrogen. It would than probably be better to cut it off so that any healthy leaves it is blocking could more efficiently use the light.

Again tho, I would wait until it is nearly dying as up until then the plant will be taking nutes (nitrogen) from the larger fan leaves and using it.

There's also a chance you could send it into shock if the leaves stem is wide enough

plants are more substenint to shock during flowering..unless the leafs dead..leave it..even being nitrogen defecient....any green means its still alive!

LET IT GROW.

don't cut, cutting the fan leaves off might create a metabolic imbalance.


"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."

hmmm. i just cut off like a shitload of lower branches and fan leaves that weren't getting any light so I would get more of a huge main bud then little lollypops.
ill make another thread later

Removing lower stems during flowering is something i also practice.

But..removing fan leaves seems a little bit backwards to what you want to achieve

"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."

I've had that problem too. There's a nice flower under this fan leaf.
what do I do?
You do not want to start pruning a flowering plant.
You've got a couple options.
you could tie the leaf up.
you could train the leaf with a small coated wire.
make it grow in a direction that doesn't shade any flowers.

The last resort. you could cut the leaf. Trim it.
you could cut the leaf in half, or remove the whole leaf.
If you cut one leaf your plant isn't gonna go into shock and die.
one or two leafs being cut it's gonna slow the flowering growth.
I've done it before, and you do have to be carefull not to cut
to many leafs, because it will slow the flowering growth.
I'm talking about a plant thats 14 -24 inches tall.
with about 12 or more nodes.
I can see letting light to the lower flowers would promote
a higher THC potency, because of the amount of UV getting to the
flowers as to being shadded.

another thing to consider is plants that have been pruned though
there vegatative cycle are more stressed to being pruned than pants that
haven't been pruned through there vegatative cycle.
