How much should I trim before flower?

They are directly under the shade leaves tho? And you basing you 'theory' on indoor grows dosent seem logical with outdoor grows and natural sunlight, I have tried many different grows and prunning plants early in growth I.e topping, main steaming etc increase yields a lot more I just can't see removing some shade leaves effecting the flower production negatively in anyway

Topping is not the same as what OP is talking about. I top all of my plants. Removing all the fan leaves or even some of them is not topping.

Its not a "theory" either. If you think that thin little leaf is enough to block all light penetration then I dont know what to tell you. This isn't even factoring in all the light that is dispersed from your side walls that the lower leaves would still collect even if the light from above was 100% shaded (which it isn't).

Sorry dude but you are just out right wrong. Go take a botany course please. Andstop believing "bro science". Not everything you read on here is correct. The only reason topping works so well is because you are removing the tip with the auxins in it. Without the auxins in the tip the side branches are allowed to grow. Your not seeing "extra" growth, its just redistributed.
Taking fan leaves off does lower yield. You are removing its solar panels, and what do solar panels do? They collect energy.

I actually have a diploma in horticulture and I think if you did some research you will find bigger leaves absorbing more light will become less productive at converting light into engery you, seriously try doing some research

Except that you're removing the upper leaves. These are the newer leaves. The older ones would be the fan leaves at the bottom. It even states that in the link you pasted so I dont see how that applies here.

And you're still ignoring the fact that the lower leaves are not 100% shaded from light by the upper leaves. If they were it would be dark down there.

Never said removing shade leaves was topping was saying prunning in general is a good thing if done correctly and yes the lower leaves May collect some filtered light but not as effectively if some of the shade leaves were removed, also your basing it on how close the leaf is to the light....

Yes but the more the leaf photosynthesise the less efficient it will become and newer less used foliage will be more efficient at it, they received some filtered light but they will be a lot more productive with direct light

Well I did a side by side with 2 clones and saw the difference in yield firsthand that comes with removing leaves. Maybe it was just that strain, but it was about 1/3rd less total yield and airy buds from removing the upper fan leaves.

Wont be posting anymore here, you have your opinion and I have mine. Good luck with your grows

If it's your first go, then stop getting worried about what other people do to their plants and just focus on growing yours. There is no need for trimming. Why not just grow them as is, and look into trimming on a later grow so you can actually see the differences for yourself.

Not sure who you meant this to - this is my first grow, not theirs and I wasn't involved in the previous discussions. It's been real educational though, I am leaving them as is, I'll trim the leaves only if they die and see how it goes.

Hell yeah good idea nice looking plant!! Been topped once?

Thanks, yep topped once. This was grown from seed and didn't produce much lateral branching so I had to top it coming out of veg so that I had a clone of it in case it was good (and it was).

I don't know if this has been said, but you are going to have an absolutely overgrown, crowded clusterfuck if you try to flower all ten of those plants in a 4x4 tent. Keep in mind that they will more or less double in height AND width within the first couple/few weeks of bloom.

I would venture that you'll end up with the SAME quantity of BETTER quality product if you only flower 4-5 of those plants instead of all 10.

They look great man. If this is the first grow maybe leave one of them alone. That will tell you for next harvest what should be cut off.

No, no one has brought it up but I have really REALLY been worried about this. Initially, I planted 11 seeds figuring maybe half would make it - only 1 didn't make it. Then I kept going figuring some might not make it, but they all did. I don't know what to do but need to figure it out fast.

I have a small veg area set aside for clones and was wondering if I could top the crap out of a couple but I don't think I can contain the growth in there either.

The thought of killing off several of them hurts to even think of, but I will do what makes sense.

Suggestions are welcomed!

Have you sexed them yet? If they aren't feminized seeds you can count on tossing out at least a few males.

They are all feminized expensive seeds from herbies. I have to prioritize, here's my situation.

My father has ALS and weed is an absolute miracle for him. He needs the 1:1 THC/CBD ratio but a good indica for sleep and a sativa for the day would be good too . I have 5 plants that are 1:1, 4 that are indica dominant and 1 sativa dominant.

Two scenarios come to mind.
- kill off 3 of the indicas and 1 CBD and pull a good top off to clone and veg and raise 6 in there
- strip the crap out of the ones that would be killed off, top and clone them and see what happens.

Thanks for any advice...

Just let them grow. Mine get pretty crowded and its never been an issue. Just make sure you have good circulation. If you really do see problems you can pull a plant or 2 in the future. Should flip to 12/12 as soon as you can though.

Edit: found this pic from last year, its hard to tell but there are 18 plants in there. its a 4x4 tent

I agree with this given the circumstances with Pangioti's father. Even though I'm not a big advocate of "defoliation" this might be a scenario where it's a good idea. Thin the plants out as necessary, keeping the best tops and discarding the under-growth.
