65 days and still throwing white pistils

Growing out TGA Vortex and have grown it before but usually other phenos I’ve ran were finished at 55 days.

This one is got 65 and looks done but is still throwing out fresh white pistils.

Any thoughts on these long flowering Sativa strains when its optimal to harvest?

Go by the crystals not the pistols

Hey , that rhymes !

Sativas are done when they are done ... some can go very long .
However as stated , look at the calyx areas to JUDGE the ripeness .
Also checking various buds to find the average Doneness overall. Not the leaf , as triches mature at different rates on different areas.

To me an easy 2 weeks .
So-called 8 week-strains are usually BETTER when run to the point of FULL maturity.

Personally I'm thinking same dont see any amber. If u want more uppity chest pounding 7 to 10 days . More zzzz help I've fallen 14 days easy. I'd be watching for 25% amber . Just an average of all the heads
