If the leaves are dying and yellowing and you are still flowering you can remove those leaves without causing any harm to the plant.
Since they are dying they are no longer using the light to feed the plant so can be safely removed.
The girl i posted above has leaves that are starting to yellow and die off but that is what you want at the end of an autos life.
It is the sign that she is ready to harvest!
For some extra info have a read here:

Great thread by our one and only Muddy!
Do you have a grow log on here P.O.D??
Would be great to see some pics of your girls!

been really fighting back pulling the leaves as they are clearly dying and you really helped me out there!! :thumbs: And thanks for the thread there by Muddy, great read. . It's my first grow and I didn't do a journal cause the computer was f'd for a few weeks. I will do a full journal next time around
very interesting thread .... im into my 1st grow ever with a Blue mammoth in DWC & it's going much better than i expected! .I only have a 5' x 3' x 2' cab & she wouldn't stop stretching ,so i had no choice but to do something as my LED was as high as it could go & the tops where way to close ... So i tied down about 10 of the closes-ed branches & trimmed all the lower ones.This was about day 45-50+ of an estimated 100 day strain ( one i think is a bit special !)... I was not gentle ! .. got a bit carried away & should have taken 2 or 3 days really ... within a day i noticed all the bud sites had turned back up ect ,like she hardly noticed ... & this was at the end of stretch .It's also opened up her super dense canopy to lower bud sites & these are packing on weight as well now.
