The color on its own I’d say is just fade/end of life, but the leaf droop and curling up is something else, as well as some signs on the newer growth.. but this late in the game I wouldn’t worry. Looks pretty good
The one looks done to me frankly. If ya got a loupe, check trichs.. if not I’d take down soon.
The one with some white stigmas / pistils still showing looks like it may need a bit more time
