cutting burn or yellow leaves.

Is it OK to cut off the leaves that are already nute burned or totally yellow? At this point they can't be doing much good for the plant right?

If they get really damages they will fall off when you brush them w/ your hand......I dont remove leaves anymore, if they fall off thats fine but I dont trim at all now.

Plant may still be pulling nutes out of the leaf, and if there is any green then the leaf is likely still photosynthesizing.

In my humble opinion you shouldn't remove a leaf unless it easily comes off with a light touch, similar to what a small wind would do in the wild.

An obvious exception to this rule is if a large dead leaf is blocking a healthy one.

i would trim them off, dead leaves can lead to plant diseases.

what the OP is explaining is damaged leaves not dead ones. Dead leaves will come off w/ the light brush of a hand, live ones will not.

trim off whatever looks dead, damaged leaves will eventually die. why not let the plants energy go toward healthy parts of the plant

Exactly wrong haha. Why not let the energy that the plant has stored in that leaf be pulled out before removing it? It doesn't take much energy for the plant to drop a leaf. Keep in mind pruning in flowering WILL HURT YIELD MOST OF THE TIME. Exceptions -do- exist of course.

NO not wrong, plus he never said he was flowering so i thing you might wanna read the post before posting. and no trimming during flowering WILL NOT HURT YOU PLANT as long as your only trimming damaged of dead leaves

plus dead leave DON'T store energy....duh

I didn't say he was in flowering by any stretch of the imagination. I merely offered some knowledge that most gardeners (of any variety of flowering/fruiting plants) knows: fruiting time is not the time to prune anything that isn't completely dead (exceptions exist). You're very correct in saying that OP did not state that he is in flowering, and I by no means said he was. I simply offered valid advice.

You're the one that suggested cutting off any damaged leaf without a mention of the photoschedule of the plants in question. This is absolutely awful advice. In fact, right before harvest many fan leaves curl and dry as nutrients are pulled out of them. This is a natural occurrence in many cannabis strains as the plants approach the end of their lives. Per your advice, OP should cut off every browning leaf right before harvest because "damaged leaves will eventually die."

Have you ever dripped a bit of nutrient solution on a leaf? It will likely cause a small brown spot on the leaf when it dries. This leaf may live until harvest just fine despite the damage, and as it lives it will continue to fuel plant growth and development. Removal of this leaf would have hurt yield unless it was completely blocking a more viable leaf (unlikely).

In short, use discretion OP! You may attack your plants in veg, but be very conservative on pruning in flower. Furthermore, completely removing a partially damaged leaf will result in an overall loss of energy for the plant. Fan leaves fuel cannabis. Unless a leaf is easily removable, the plant probably still wants it and CAN PULL NUTES FROM IT.

Hope this advice helps.

cut cut cut dead or yellowed leaves go

Thanks for the advise everyone. I know its usually 50/50 on the topic of cutting fan leaves. I usually don't, but these were my first autos and I burned them pretty bad. I will just try and bend out of the way what I can and if they break off in the process then oh well. Also they are well into flower, day 43 from germ.

I've done it both ways, and can I say there is no real significant difference between the plants that I took fan leaves off and the ones that didn't... If anything I got more bud from the plants were I removed big damaged leaves as the light could penetrate further... Don't remove too many leaves, that's over stressing the plant... Remember this plant is a weed... Its a hardy weed that can thrive in all sorts of conditions... It grows on almost every continent, pretty impressive.... Don't treat it like an orchid, cause it aint one.... Do what you gotta do... There is nothing kind or gentle about nature is there????
