Over the last couple of months I've started defoliating, at first I removed very little, but recently I've been removing many leaves at a time, not complete defoliation (fans getting good light and not shading out the center or other buds), and also not on a set interval like day 1 or 20, but when I notice new fans have obstructed the interior or completely shading out side shoots which can be every 3 days, and i have to say I'm really liking growth a lot.

This is being done on some clones I've flowered and harvested at least twice so far.

I've gotten pretty deep into gardening over the years, and I general plants do better with environmental stressers, like cows grazing grass improves growth, and it seems to reason with our limited light penetration from even the best of lights, that the combination of controlled stress from defoliation and the increased light reaching all the buds sites that you'll get better growth, and better doesn't necessarily mean more yield, but better medicine overall

The reason cows grazing might improve growth is because they're fertilizing while they're eating and then moved to other locations before they eat all the grass. Goats will destroy a field. People use them for brush control and clearing land. Ain't no grass growing back better after goats get done with it.

I'm going for the complete opposite experiment this time and not defoliating or topping my plants. I went full schwazz last time. My walk away was it would work pretty well if you had a high plant count similar to a sea of green. Aside from a plant here and there, I have always defoliated from "somewhat" to "full on scorched earth." I want to see what happens when I just let them do their thing this time.

I love some experimentation!

The yellow leafs should be kept alone. It is a natural process that the plant move the metabolism products into lowera and older leafs to discard them. Once the leaf is pointing down, it is not recieving anything, you should remove it, but yellowish that is still standing should remain to mimic natural process.

It looks like you defoliated the two healthiest looking ones. The leaves on those plants are pretty yellow. You really need 4 healthy plants for a side by side like this..

If I defoliated the control and the lollipop they would have the same healthy green undergrowth that the two swazzeed clones do.

The 4 clones looked about the same before defoliation.

The control and the lollipop were the two tallest plants in the tent.

Its a delemma - swazee the two bushy plants and get a good harvest or leave them and hope for some decent data.

Correct me if I'm wrong here, but isn't removing yellow leaves from unhealthy plants vs leaving them, a different experiment from defoliating healthy plants vs letting them bush out?

Once leaves are no longer green, they are no longer a source of energy for the plant, they become what's often referred to as a "sink" (meaning it's taking energy from the plant. It does actually require energy from the plant in order to break them down to a point where they will drop. That's what we want to keep the leaves on cannabis plants green well into the flowering period.

Not sure about taking energy. What you are referring to is more related to trees shedding leaves in fall. The yellowing of the leafs while vegetation or during flowering of our famous plant here is more like a type of excretion the plant is doing to get rid of metabolism undesirable products and it is completely normal. That's why you should leave the leaf on the plant until it is ready to come off. It's like going to the bathroom for animals. In fact if you rush taking leafs of as soon as they start loosing the lush green color, other leafs will start getting yellow sooner. Remeber the plants don't have a.hole and want to discard these non-gaseous products. https://www.scienceabc.com/nature/how-do-plants-excrete.html

So, are you saying that you believe that yellow leaves are a source of energy of the plant? You do realize that it requires energy for the metabolic functions to break down the leaves and drop, right?

I was under the impression that you did not pay attention to your teachers in elementary, but you proved me wrong. Now I know you are so high that you can't read nor write with cohesiveness

Oh snap, zing! You really got me there didn't you! Obviously you smart, me dumb. Me know nothing.

Please tell us more about how to do it right, and show us your plants! We all want to see how geniuses like you do it!

Waiting on my seeds to arrive from England while being interested in this experiment. No genius. Apologize for my earlier comments. I was aiming to have some fun with you guys and interested to know what is the latest about plants discoveries which I thought was a science already nailed down. Obviously not.

Id get rid of yellow leaves. They can be a source of mold.

Yellow leaves are not a good sign. Its usually a sign of some kind of stress, or not enough nitrogen, or even Magnesium.. Or lack of enough nutrients in general Ive seen 10 foot tall plants with not one yellow leaf. Its not a natural process until the very very late stages of flowering to see some yellow leaves.

To me, in the bottom photo, the 2 plants on the top look hungry, or theres a PH problem. The plants also appear to be pale.

In the top photo the plants are yellowing from the bottom up, which is often a sign of lack of Nitrogen.

There's way to many yellow leaves.
