Yellowing Leaves??

I have 6 girls in a closet grow. Plenty of light and circulation. The fan leaves are starting to turn yellow. I was using SBB Super Bloom A and B for flowering. I am about a week or 2 before harvest (Trich's all clowdy for the most part) 48 days into 12/12. I really don't want to add any newts now. Just wondering if I should worry...or is this normal this close to harvest?? Thanks

did you start flushing too early?

do you know the strain and when it should finish?

if it's 2 weeks away from harvest, maybe feed it nutes one more time, if the yellowing continues it should be getting closer to finish, cloudy trichomes is a good time to harvest.

p.s.

leaf yellowing is normal close to harvest, 48 days is a decent early finisher.

I actually have 2 different strains. One is clearly an Indica and one is clearly a Sitiva. Not sure exactly which types. These are 2nd gen clones from seeds a friend got me. Maybe it's closer to harvest than I figured.

The plants are using up their nutes since you stopped feeding them.
They also do this at the ends of their lives.

The will turn yellow and start to die.
No worry.
You are getting ready to kill them anyway.

If the trichs are cloudy to amber you should flush and let them dry out then harvest.
