How to really know when to flush

Hi. I think I’m about ready to start flushing. Girl Scout cookies about 3 months along. It looks to me almost ready to flush about two weeks left to harvest. Not the best pic. How do you really know when to flush ?

When the fertilizer manufacture says to. We have no clue how you're feeding.

Flushing is anecdotal and not really necessary at all. Just taper down your feed as you progress in flower.

no need to flush, as above, just give them less n less food. dont starve them

What’s your medium

I am using the fox farm ocean forest and happy frog soil. And been using the tiger bloom fertilizer.
so many different opinions on flushing. Thank you.

With FF soil and nutrients, the chart does advise a plain watering every third watering. But, as stated, skip the final flush. You're just starving your plant at its most critical stage of development

No reason to flush soil, ever. Flushing soil turns it into rock, sand, and salt.

Wow thanks for the tips. Will not be flushing. Just going to taper down the feeding. So many sites out there saying flushing is necessary to avoid bad tastes and something about the way it ashes too.

Bad tastes are avoided by properly caring for the plant; not over or underfeeding, not over or underwatering, and not over or underpowered lighting. That, and genetics. Flushing DOES NOT improve anything other than color fade, which has no correlation to overall flower quality.

Thanks for the tips. This is only my 3rd grow. I feel it’s going to come out pretty good.

It looks good, keep up the good work!

Flush is a stupid way to drown plants. If organic just water normal last couple weeks. Flush term should only be used if way over nutrients used by dumb or accident in an attempt to save them with 3 or 4 times normal water. Flush term is not normal water its what a toilet does. Get the term right. IF not organic thrug shoulders....

Just a beginner here. Trying to get info from the web and advice where they use the word flush. Lots of differing opinions.

no problem. I was new a while ago. Got it dialed in and giving back from experience now. no bs or hearsay. experience.

I give plain water for a week. I don't FLUSH them or get tons of runoff, I just keep the rootzone wet and in doing so the remaining nutrients/salts are absorbed into the rootzone and used up by the plant. By the time I harvest my plants aren't really drinking a lot anymore anyways so why would I add a bunch of fertilizer to coco root balls that I'm going to chuck into holes on my property?

Same. Once I see the plant is ready. I give it another week & it survives on nothing but good old city tap 145ppm I don't even adjust the 7.6 ph.
Water til I get a drop or 2 out of the bottom.

Just feed water the last week/2 weeks. Don't flush unless you have PH problems or you've burnt your plants.

After you're done wiping and pulling up your pants, thats probably the best time to flush. If you do it while you're still sitting down then you risk a splash.
