i have 4 plants that are 6 weeks old (4week/veg.. 2week/flowering) under 600w hps and i was wondering if should i cut the fan leaves on the bottom since they dont really get too much light. Should i leave it or cut them?

This is what i do;
If the fan leaves look more dead and shrivled then alive and thriving; If it looks like its take up useless nutrient and space, get rid of it; otherwise your losing your PHOTOSYNTHESIS!!
I cut them at a 45* angle with a sterile razor; They may grow back, or may not.

Hope i can help.

As the leaf gets yellow/brown and crispy, the plant is sucking up energy from the leaf because it's not receiving enough light to photosynthesize properly. Even though the leaf is not producing energy the plant is still getting energy and nutrients from it.
I don't pull or cut any leaves from my plants unless they look poorly and are blocking light to a bud site, although most of the time it's just as easy to move it.
The plant knows what it's doing, when it's done with a leaf it will drop it, for you to pick up.

Just to fix some misinformation, fan leaves do NOT grow back, ever! Maybe you're thinking of node growth?

Also, don't cut off fan leaves! If they're ready to be removed they should be able to be pulled off with your fingers with no effort.

Leave leaves alone! Removal of healthy leave hacks up a healthy plant. Removing large or shade leaves DOES NOT make plants more productive. This practice DOES NOT supply more light to smaller leaves and growing tips. Plants need all their leaves to produce the maximum amount of chlorophyll and food. Removing leaves slows chlorophyll production, stresses the plant, and stunts its growth. Stress is a growth inhibitor. Remove only dead leaves or leaves that are more than 50 perfect damages.

Don't ever remove fan leaves before harvest for several reasons.

1. The fan leaves convert and store more energy for the plant than any other leaf. The more energy the plant generates the healthier the buds that is just millions of years of genetics at work.

2. Even if the fan leaves are yellowing in late bloom I do not remove them until they are almost ready to fall off. The yellowing in the fan leaves at late harvest is the plants metabolism at work. She is transferring all stored energy in the fan leaf to bud production. It is the easiest source of energy she has late in life. Once again millions of years of genetics can't be wrong or we wouldn't have weeds to grow now.

If it is on the bottom of the plant and not reciveing any light then take them out,you will get better air circleation and why waste valuble nutrients on the bottom of the plant that will only give you very little nugs any how get the nutrients to the top part of the plant.should have flowered smaller this style of growing can be great for massive yeilds because all the plant recives light not just the top.

IN MY HUMBLE OPINION, When a large FAN leaf starts yellowing, say it is half yellow, that means in the photosynthesis process, that leaf has ate nutes, sucked in some LIGHT and made food for the plant and buds and NOW, half of that is gone, or used or consumed. Well, what about the other half? Can it not it's energy still be used or consumed?
AND when it is ALL consumed or used, that leaf will naturally just fall off.


Years ago I tried removing lower fan leaves to allow more Light to penetrate in. When i did, the plant went into shock for a day or two, and quit eating or only ate half as much, and just went on "stand by" mode. Then, after a day or two, suddenly, I saw that big fan leaf replaced by a new leaf, and I saw my plant use the energy to replace that leaf, more than it used it to grow bigger and make more buds or bigger buds.

I now believe that removing fan leaves is pointless, and that a leaf has a purpose and will serve that purpose until it is dead. Then it will fall off.


Don't ever remove fan leaves before harvest for several reasons.

1. The fan leaves MAKE AND STORE energy for the plant. The fan leaves are doing a process called photosynthsis, and it is the most important part or task or job the plant does, to make it grow. They make the FOOD, the sugars and carbs needed to grow.

If you remove a FAN leaf, the plant will stop growing taller until it can replace that removed fan leaf.

Removing a healthy fan leaf is a big waste of time..they are rapided replaced,, unless you are in the last few weeks of flowering.


2. Even if the fan leaves are yellowing in late bloom I do not remove them until they are almost ready to fall off. The yellowing in the fan leaves at late harvest is the plants metabolism at work. She is transferring all stored energy in the fan leaf to bud production. It is the easiest source of energy she has late in life.

Sorry to revive an old post but two of my plants leave's are burned...fairly bad. However, my plants are still young - only 16 days old.

Should I leave the fan leaves alone or cut them?
