Flush or not

Looks like some paling on lower leaves and creeping up already (n-def)... i'd becareful of restricting building blocks as it's already deficient in at least 1 of the elements involved in nutrition of a plant. Plants need less nutrients overall once into reproductive stages, but it still needs it. I'd continue to react to the plant... reduce for creeping toxicities and avoid creeping deficiencies, just as normal. visible deficiencies and toxicities tell you exactly how much the plant is using it... a proper balance of provision vs use = healthy looking plant. Can't cause a problem simply providing what the plant can use.

I would only give water instead of nutes on the last week before you chop and that's a few weeks away. Not excessive amounts of water just the same as you would normally use.

Pretty lady, you can but your running an organic fert, so you might be ok. Instead of "flushing" just stop feeding and only water till you cut it. Really nice plant good luck

It would seem you are still a couple weeks away from chopping. There are much too many white pistol hairs around, which means the flowers aren't near done growing. Flushing now may stall production as she won't get the nutrients she'll be asking for the next couple of weeks, if you let her flowers thicken up more that is.

NOT

Yes, scrubbie is right too. Your plants need more than 2weeks to finish. I would aim for a harvest in late week 9, early week 10. They not maturing right now, they still growing in budsize a lot

She'll definitely take longer than 8 weeks. From what I see maybe 9 weeks, but more likely 10. No need to flush, just stop feeding and water normally with plain water for the last week or 2.

Don't really trust breeder timelines too much unless you're dealing with so many plants it's impractical to individually judge them. Use a magnifying device and look at the trichomes. Breeder estimates are just that, estimates, and varies by pheno and the conditions the plant is grown. You're getting near the finish but might run a couple weeks longer than you anticipated. You'll find a lot of the community here has a hard time differentiating between a standard flush and a harvest flush, kinda like regular defoliation and harvest prep defols lol.... Anyway, you certainly have the option to abandon your nutrients early and go straight water. If you plan to chop in a week does it really make sense to add nutrients that might take a week or more to absorb and process? There are nutrient stores in both leaves and potentially media that can be utilized, to a point, and is an avenue to save a little money on your ferts. How early depends on your media type and consistency. Soil holds onto stuff longer than coco. Health of the plant matters too. A plant that's already struggling with deficiency will progress harder. Typically in soil I might start about 10 days out, in coco maybe 5 days. In DWC, I usually just start topping off with straight water once I notice they're not feeding as hard. You could do a tank change to plain water early but I'm too lazy for all that lol.
