Problems or nearing harvest?

Hey guys, thanks in advance for taking a look and any tips you may have for me. I’m at 8.5 weeks into flower of my second grow ever, this time an 8 top mainline Super Silver Haze bag seed micro grow. Medium is 1/3 ocean forest, 1/3 happy frog, 1/3 perlite. Nutes are megacrop plus a drop of molasses to 500ml of water every other day now in flower. I think I may have gone a bit heavy on the nutes a few weeks ago but I backed off 3 feedings. Any idea why the older lower fan leaves are yellow and dying? Am I reading the end of my grown needing to start the flush now or can I go another week?

thanks!

Leaves start to yellow and die off when its nearing the end of its life cycle

They are just burning up the N that they dont really need anymore at this point. They just want/need the P/K to finish up flower.

Some plants yellow off and turn colors at end of cycle and some stay green. She looks great I just pluck those leaves off

How much longer do you guys think I have? Should I start flushing soon?

I'm not a huge nute grower so hard to tell but if ya think your around 2 weeks out prolly just water.

What do you guys think? How much time left?

Couple weeks ... only look at calyx area for “ average “ doneness on multiple tops. One last good pk feed. Then water only til chop .
No flush crap ... you are weening nutes down instead. There is still ample white pistils ( another maturity indicator ) . When at least 80% or better on pistil color off and recede will put it at maturity.

You can also partial harvest the mains as they will finish first then let mids / lower buds time to finish .
You can also “ force the flower “ a bit by dropping cycle to 10/4 for final weeks to push it.
Remember it’s too easy to chop TOO EARLY vs. chopping Too late.
