Sugar Leaves dying Around Nugs

Troubleshooting
1

Last week week I noticed a brown spot on a single sugar leaf on one of my Northern Lights, and I didn’t think much of it. It is now week 6 of flower and the problem has spread to a dozen branches and the whole plant is a shade lighter than the others. The other Northern Lights and all 4 of my Granddaddy Purps seem fine. It starts with a copper/tan patch at the base of the leaf by the nug and spreads out towards the tip of the leaf. Any insight would be appreciated.

How many weeks has the plant been flowering?

She is in the middle of week 6

I expect it is end of life fade with nothing to worry about. The plant is done growing and is now focused on ripening flower.

That was my first guess. I just thought it was odd because the other NL appears much closer to harvest with no fade in sight, but I guess that’s a fallacy on my part for believing the two would be exactly the same. thank you for your input.

Plants can be like people. No 2 are going to have the exact same behavior and appearance.
