Flushing ?

In currently about to flush one of my plants and I was just curious when I should start nutrients after the flush?

If you HAVE to flush.. feed with the last portion of water you give the plant. Then give it time. This thread will self destruct in 00:30
I think my plants are in nutrient lockout( thats what ive been told at least) so in pretty sure I have to

Downward clawing leaves (dark green as well) indicates Nitrogen Toxicity. The plants don't appear under watered to me.

If you do a flush you would give plain water then start normal base nutrients right after once the plants are thirsty again, don't give plants plain water for more than a couple days at a time, when you near harvest reduce your fertilizer strength instead of giving them plain water and stressing them.

So instead of flushing when in near harvest I just reduce nutrients ?
Yes feed a basic strength like you would in veg and do not add any more supplements or additives, just base nutrients. If you give plants plain water at any point for days at a time it will negatively impact the plant, you can't flush out what is already in the buds but you can flush out the roots. Depending on what size pot you have a single flush could be detrimental if all the nutrients are washed out.

When I think "flush" I think of it as feeding the plant until normal runoff with plain water when EC in the roots is too high or you get salt buildup or something of that nature. By the time that equalizes itself 12-24 hours the roots are going to potentially drop to a dangerously low EC/PPM and then your plant is starving and stressed out.

You can't remove what is already in the plant you can only remove what's in the growing medium (soil, coco, hydro w/e).

Per Aptus Bible 7 days of a cannabis plants life is equal to 10 years of a human life.

Some genetics thrive on stress, some people swear by 7-14 day of pure water before harvest. Some growers will feed full strength base nutrients & supplements until day of harvest. Try the different ways and see what works best for you, grab an old composition booklet and note each plant from veg to smoke.

Personal Trial & Error with your setup, environment and genetics is going to be the best thing you can do. Take clones of the same plants you enjoy traits of so you can fine tune each run where its perfect start to finish.

Update I flushed but now (and I think even before I flushed) my bottom leaves are turning yellow and it seems its going up

Feed them next time with a tad more nutes. Maybe 100-200ppm more than last feeding. UNLESS you are already feeding the max dose.

Some leading questions:
-What is the medium you're growing in, & what sized pots/bags?
-What was your runoff EC last time you watered (not fed)?
-When feeding/watering how much fluid were you pouring through and how much runoff were you collecting after?
----
-When you did 'flush' how much water did you put through each plant, and did you measure runoff EC along the way?
-What was the final EC at the end of your flush? what was the EC of the water you're using?

I'm not much more than a rank amateur, but the photos doesn't scream that things are bad enough that I'd right off suspect lock-out? Obviously too much nitrogen, etc. though.

I've flushed before when my EC was up in the 2.4+ range, mostly due to poor watering/feeding technique. At that time I flushed down to .7EC (my water is .48EC), once I reached .7 I fed with about half the strength I'd been feeding so they had something to work with.

Once I nailed down better watering technique, I haven't had a situation where I suspected lockout since.

A mixture of coco black and white peat worm humus and perlite pre fertilized 14-16-18

im in 3 gallon pots
anf as of the ec im honestly mot sure I dont have an ec meter yet

I think you're putting the cart before the horse if you can't measure what's coming out the bottoms of your pots. You suspect lock-out but without knowing how much nutrient waste is in your medium its at best inconclusive. Spend the $20 or less and get something to test your EC.

I'm not a fan of kitchen sink mixes of soil/coir and whatever. Each medium excels when you treat it individually (and differently) but so many people with slurry mixes of ingredients end up here with fail-questions. Most of those have copped their mix from some rando on youtube.

And about the lockout I was told I had nitrogen toxicity by multiple people and since its my first time I took their word
