to flush or not to flush. .

That is the question. I'm 5 weeks into fleeing this strawberry today and I was just doing some bored reading and came across something about flushing coco every 3-4 weeks to drive nutes to the bud sites... but also, upon further investigation, I came across something that said you don't have to flush coco at all. . .even before harvest.

I have always flushed (at the end) I'm just curious is in missing out on something by not flushing more our by flushing at all.

Thanks buds!:leaf:

I guess like everything else, some people flush and some not, personally im feeding
with the GHE chart so basically they recommend to flush just like you wrote
every 3-4 weeks + before harvesting. I dont think yuoll find just one answer for your question

* Its really important to check your R.o water, just to be sure your o.k.

Never flushed unless I had a problem. Way too many threads on this topic. I'd recommend doing both side by side and see which one you like better.

So why do you just use water at the end?
Sorry for my newb-ness..
I understand that the plants, like most, will naturally uptake less nutrients in the fall/end of life or during senescence.
But doesnt the grower already account for this by feeding less? Not only reading the plants needs at its current state but looking ahead as well, especially if in soil or using ferts that must be processed?
What does this only water feeding accomplish?
From my minor and short experiences with cannabis and other plants, they will form an abscission layer in the leaves when in a low nute environment. This stops overall depletion of nutes as the leaf is not completing photosynthesis and not taking anything in from the stem and the plant,so instead of a net loss the plant cuts off the leaf. This keeps the levels of nutes in buds stable.
This constant stability is pretty hard to disrupt.
But nutes in buds arent necessarily bad. I like to compare weed with similar and more studied industries like tobacco. For example through extensive studies not only on burn qualites of the herb but also the cigarette theyve found Phosphorus to expand when hot and give a more complete and efficient burn, calcium provides a whiter softer flaky ash that can slow the burn..and when you think about it, after being burned the nutes are what makes up ash

Well guys here's my reason.

Yes, I'm a coco grower. I don't think I would flush until the end of my flower cycle but noticed that the top of my coco was hard, crusty and had salt build up. So I did flush on 4/20 and the coco is looking better and spongy again.

I probably wouldn't have worried about it other wise.

I only have about 3 maybe 4 weeks left so I'm gunna pump her with add much as she can take again and flush once more in 3 weeks.

Just an update.

I agree that if the plant looks healthy and is thriving, don't flush... it clearly has everything it wants and isn't stressing or having lockouts...even though my plant looks good...I went ahead and flushed to get rid of the salts up top...

would I do it again... probably not.
Just my $.02

Thanks for the replies everyone!

when I used coco, I would flush about every 2 weeks. I would feed normally around 1.0 to 1.3EC and for the flush cut it back to about 0.4EC.
when the trichs were ready, I'd give 2 days of just RO and then harvest.

i was using cutting edge solutions (about the same as GH) in the H3AD formula for coco (6 ml Micro, 9 Bloom)

for the "during" flushes, I just cut the strength of my nutes to about 1/4 strength for 2 days then back to normal.
for the "final" flush, just RO water. didn't even bother to pH it.

How long have you been doing the H3AD/Lucas formula?

I started with Lucas and still use it now in hempy buckets. so since 2009

when I used coco, I switched to H3AD.

i didnt' care for coco much. growing can be difficult enough and having issues with my grow medium was not acceptable. i use growstones now and perlite was a good medium too.

White ash, huh? Love the nutes and ash theorys. And nutes, don't make up ash. Its food for them. I had tacos,last night. But my shit, came out brown today?

Nutes are food for ash? Lol
Why dont you, i dont know google "wood ash composition"
This is what google says without even clicking a link

calcium carbonate as its major component, representing 25 or even 45 percent. Less than 10 percent is potash, and less than 1 percent phosphate; there are trace elements of iron, manganese, zinc, copper and some heavy metals.

These would be non flammable compounds that stay behind. This is what remains as the white ash when you burn charcoal weed or anything else. The varying composition is what i brought up from reading studies on tobacco and burn qualities


But not only do you use foul language, talk inappropriately about bowel movements nonetheless , but you also eat nasty tacos (particularly nasty if they left your system that quickly)

All this concluding you are either young, ignorant, disrespectful, not very intelligent or all of the above.

Normally an argument must be debatable but there is no logic or science behind your post.....

If the top 2" of your coco is drying out enough to see salt build up you are not feeding them often enough. Established plants in coco should be feed at least once a day. I never flush but do allow 20% run-off once a week and the last week of flowering tape my feedings to 0 ppm for the last watering.

do u know anything about nutes? As u said, ash will tell u what's in it? At the end all ash will be white. And I would never compared, marijuana to tobacco?????

Also, what your talking about is residue, from ash. Nutes we use for growing, will not show up color in the ash. Show the facts, not half facts.
