Trimming fan leafs

I'm on day 41 of flowering and many of my fan leafs are turning yellow/ crisping. I've heard many people say not to trim anything and vice versa. I've already trimmed some of the dead crisping leafs but should I also trim the yellowing fan leafs blocking newer growth? Does anyone agree with this article I'm about to cut & paste?

Leaves that have reached their final size and are ageing will stop producing chlorophyll and start changing to a lighter color, often yellowing and showing purple petioles (leaf stems). This is when the leaves' capacity to produce sugars starts to diminish, so they are the ones to take out of the way to allow Sunlight to fall on the younger leaves that are producing at a higher rate. The older leaves, even though larger, are no longer very productive once they are not dark green anymore. By the time they start looking pale or discolored, they are not contributing anything to the plant at all. Obviously, the lower leaves are the oldest and the first to age. Old leaves can be removed at any time they are shading younger ones, but try to never remove a leaf in its expanding stage because it is producing at full power

I agree with the artical but I bet you will find that there are a lot of people on here that disagree. My thinking is that if it's dead it is not needed and is only a hinderance to the plant. I have also heard that it is a good idea to trim off smaller fan leaves if they are blocking a large bud mass below it (If the leaf cannot be moved out of the way) I am actually trying out this theory on some right now, sort of a controlled test. and from the looks of it at half way through flowering I would say that trimming off a few sugar leaves here and there to give more light to developing bud sites down below is a good thing. I think that you shouldn't get too carried away though for sure. hope this helps. there are a lot of other opinions out there though and it really comes down to what you think works best for you. peace.

What he said.

It's perfectly ok to trim fan leaves this late into flower if they are already dying off. Trimming healthy fan leaves that are blocking light from getting to clusters of buds is also ok.

Thanks yall I feel alot better about cutting on my babies now

I always trim mine.
In fact i suppose you could say near the end of the flowering cycle my plants have a skinhead leaf haircut

cut half of the leaf off, and then a week later cut off the rest. Cutting the whole leaf off at once during flowering will take attention away from producing buds

Interesting never heard that but can't hurt I'll try it

I don't agree with that as you just stress the plant twice on one leaf and having trimmed in half leaves can lead to disease.
I always make a clean on the leafs stem as near as possible to the main stem

You're wrong and i disagree with that. disease normally sets in an exposed wound on a stem not a leaf. and yes trim the leaf completely off nearest to the main stem at the END of the week. Its not stressing the plant twice, its not stressing the plant AT ALL instead of once. Otherwise, why would I even bother?

Ok regardless of whos right here i read out of that same article that when cutting fan leafs cut the petitoles (however u say it,, stem to the fan leaf is what im talking about) to cut half way down and not too close to the main stem. Reason being, if infection sets in, it would have to travel farther to the main stem making it harder to spread to the whole plant. I dont know about all of that, but why are yall saying to cut it as close to the main stem as possible, is their a reason there?

Huh? you have evidence? Photo's of your succesful grows? Indeed proof of any kind?
Half cutting minor fan leaves on unrooted clones (which by their nature could be described as reasonably stressed) by some people who have a gut feeling it helps (I am not one of them) is one thing and by all means agree/disagree, but to call someone out as wrong needs a bit of proof in my book, and I do not believe you have the hard evidence required

It could stress the plant leaving a long ass leaf stub sitting there to isolate disease sounds dumb. I've never heard of that. cutting close to the main stem it will heal up quicker, faster. LOOK just cut the leaf in half with sharp scissors make it a clean cut and you will be just fine.

Would you listen to yourself? you sound like a bitch right now. why don't you go wipe your ass and go to sleep.

Half cutting the leaves of an unrooted clone reduces transpiration. clones can't afford to loose any moisture in thier leaves without any roots and thats why young plants do better in the 60-70 RH range

If you look through any of my journals or my gallery you can see my buds and my plants.
I have been growing for a long time and i can tell you that the best experts in the world will tell you to make clean and precise single cuts as near to the stem as possible.

Cutting leaves in half is for clones only.
I meant no offense i just don't agree and nor do any other professional growers

A clean cut close to where the petitiole (is that how you spell it) joins the main stem is where you should be trimming fan leaves. Extra cuts can spread disease and infection. Cutting leaves in half on flowering plants and then cutting it again will simply begin to stress the plant and could cause your girls to hermie.

Well I've tried it your way and it works. I've tried the technique the way I've been saying as well, and it works better. I got the idea from the cannibus grow bible by greg green. Have you tried both trim techniques like I have, or just that one? If it doesn't make sense to you then don't try it. i don't care....

I have not tried it for flowering plants because I do not wish to send any of my plants into a stress-induced hermie form. Clones I have no problem with. Just like you said about your opinion, I simply believe my way works better.

Oh. OK cutting a leaf is going to make a plant produce seeds all of the sudden right? Now you guys are just starting to make shit up
