Why should you not trim leaves during flowering

[birdboy]

I was told that during flowering, i should trim the larger leaves off that are hiding the buds. I did do this and have trimmed several leaves off the plants giving the plant more light for the buds. Now i have been told NOT TO trim that the larger leaves help light intake.

I have noticed some of the plants are wilting on the bottom.
is this from trimming too much.
What is the affect from trimming the leaves that i will have?
I am pannicing now i have gone this far i am afraid i might have messed things up.
any input would be grateful
thanks

One word.... HERMIE! When you clip off fan leaves, branches, etc. it causes stress to the plant which could cause hermies. The key is to try and not cause ANY type of stress during flowering. Also, your fan leaves take in the light/feeds your plants. I could get more in detail with it but I'm :stoned: and lazy at the moment! Someone else will stop in to finish what I started!

Hello birdboy,

First thing is...don't panic, it's a plant that is pretty forgiving. Again tho I'm working without a pic of the plant, so I'm not sure how much you took off.

Like I said on the other thread, generally it is not a good idea to cut off leaves since they gather the light to drive the plants growth, along with nutes. But you said you are only 3 weeks into flowering and kept the main top fan leaves. Your plants may do fine with what it has left, maybe slow growth rate a little, maybe cost some finished weight. But they will continue to flower and I doubt they will turn hermie just from that.

The wilting lower leaves are probably not from the trimming, could be any of a couple of things. Keep in mind as the plant finishes, lower leaves tend to die off first anyway. I trim lower branches sometime because any buds from there are going to be smaller anyway and I'd rather see the plants energy used for the larger top buds.

I am assuming that you grow fairly large plants (like 4' or so) like most people on these boards, so if you cut less then 1/3 of the leaf mass total, you should still have enough "leaf power" to get the plant done. But like I said before maybe a little slower and with smaller bud. With a little luck you might not loose anything....and it's better to lucky then good.

Next time consider this, if you are not growing to a production schedule; when the top buds are ready to harvest, cut the plant in the middle and harvest the top half of the plant. Then give the bottom more time under the light (a week +/-) so the bottom buds can plump more and finish to the trichome level of your choosing.

Good luck and if you could post a pic here, I will try to help you more.

I havent' heard about the stress factor, not that I'm doubting it...I'm very new as it is, so that's some good info. But what I've done so far is to gently bend the larger fan leaves, that are only directly blocking target sites, below where I want the light to get to. That way I keep the light catchers, but they're out of the way.

I have read at least one article about a succesful grower that does trim very discretionately...for what that's worth.

I take cuttings from plants 2-3 weeks into flower without a problem. But severe pruning of a flowering plant will probably cause it to stress.

Another method of getting more light to the bottom of the plant is to have a oscillating fan blowing on it. Just like outside in a breeze it causes the leaves to move around and the shadow pattern changes constantly.

good advice :thumbsup:

don't cut off leaves... leave them in tact

Typically what I do is tuck them out of the way. If they are really in the way then I take the leaf and cut half of the tips off (cut at the knuckle of the leaf) this seems to be a happy medium. With that said when I do this I might only trim like 20 leaves across 30 plants and I'm not actually removing them but rather just cutting off the overhanging tips that are blocking light.

This technique has worked well for me. Previously when I removed the entire leaf/stem I found that the the budsite at that leaf/stem node seems to lag behind.

That's how i would handle it.:jointsmile:

i slaughter my plants somewhere between day 10-14 of flower and clear out most of the bottom branches and it results in heavier colas

but i never top or take any of the main branches, top fan leaves stay unless theyre preventing light penetration and i try not to remove anything that doesnt need to be, cause to much will decrease yeild especially off the tops

do some research and find what works in your garden for you, lollipoping is a technique some use

Hello,

O.M. I (try to) grow similar sized plants as yourself; short, single cola plants, so my plants have very minimal side branching when they are triggered into flowering. Side branching intensifies in the first 3 weeks of flowering, and only then does it become a nuisance. My first question is, do you cut lower branches off? Secondly, when do you do this, so that it doesn't impact yield? Thanks.

good advice :thumbsup:

I thought you'd like that, I even thought of you when I posted it....

....I was trying to "emulate nature".
