never but its best used most in early to mid flowering when she pumps out her last set of fans if they are covering bud sites you can remove them to let light get to the bud but I would only do so if you couldn't move the leaf or tuck it somewhere out the way every healthy fan you remove from her is taking away energy she could be using to grow faster and better :)

Big leaves keep or not?Question for all the growers in here. When I can cut those big fan leaves on my plant? According that this is an acceptable procedure. My plant is still in veg with around 11 nodes. It seems that those big leaves put in shade the side shoots, should I remove them or not?

Trimming My plant is dense, all of the stems and flowers are close to the stalk. I was wondering if trimming all of the sun leaves to make room for sunlight would be a good idea, I don’t want to hurt my plant.

Defoliation in flowering stage Now that she's in the flowering stage is it still safe to trim and tidy the big fan leaves to help light penetration? If so, how much can I take off? What leaves should stay or go? Is it safe to keep training her new branches? Thanks again, all help is appreciated.

Defoliation for better ventilation?Should I defoliate/prune to ensure better ventilation? I am going to flip the plant soon. It is quite bushy with big leaves and sometimes it is difficult to water it as there are a lot of leaves down there. And when is it better to put the net? Before of after the flip?

It is the end of 9th week (5th of flowering) and the hairs are becoming curled and brown. Now, I cannot see if thricomes are milky because I have no microscope so my question is: how can I understand when to flush the plants? Is it now the right time or should I wait a week more?
