It's because you are building up salts inside the rootzone,, flush it hard once a week and you won't have a problem in future

How do they do this,, why do they do this,,, i mean I amend coco,, but makin it runoff at that ec is weird,, its basically way stronger than soil,, and whats the npk ratio,, how is this meant to work,, it must be part of a funny "easy to use" program,,

personally,, I'm starting to lean towards using coco for rootball establishment,,, after years of rockwool and root riot,, i have finally decided to switch,, , you need an auxin heavy to cytokinin ratio to initiate root differentiation,, this ratio is how clonex works apart from iba as the active ingredient (rooting hormone) ,, later in the plants life you want a branching agent,, but in the early stages it's all in the roots,,,

a lightly ameded coco with a time release fert,, full of perlite and inoculated with nitrogen fixing michrorize (for clones) ,, i just can't think of anything better,, feed it some tea,, root stim,, rhizopon,, boom,,, then it's a different mix for flower,, you will need to adjust all the variables to initiate different stages of groth,, i guess its all in the hips bro,, bit of benificals and your off,, try to get the benificals working to make your food and brakedown the amendments in your medium,, the absorption is better with benificals producing it for you

Definitely pre-rinse your coco until the runoff is a very low ppm. There is a lot of excellent advice on this in the coco forum, which includes some on pre-charging it at the same time, no?

yes Douglas i will do this next time.my local hydro shop said i shouldnt
be testing run off. i rang mills about high EC the said dont worry as long
as its going right. i phoned mills for advise on there nutrients.guy said
i dont have an answer for you but i will ring you back.that was 2 days ago.tbh i might change to canna also there nutrients the EC jumps about.atb Rab.C

Just this guy, ya know?
No chart shows up in the last pic. Also I don't see a pic in that first post either. If they are albums, make sure set to public. If they are publicly hosted photos, make sure the domain hosting them supports https. A lot of places screw up their TLS setup. I'll leave this up for posterity, but I see all pictures now. :tiphat:

Personally I suggest the canna aqua range,, fed on nft or coco,, brings out a good flavour,, but hay,, Milla pays the bills,,

I would just use the Canna range if I was going to go use coir. I never used to flush weekly as it was too much of a PITA. I just fed them low EC with additives hard for 6 weeks of flower & then flushed them the once & then faded them up on tap water.

I used to water a few times a day by hand or with timers & I would use 1/4 strength A&B 1ml per L and that would grow cuttings or mothers & full flower mode & would fade up & burn reasonably clean without the flushing.

I did occasionally feed high then low in peak growth points to wean them off with tap water from week 6 onwards.

Flushing or diluting can help against salt burn or nute stress but that don't always show up on beasters..

Don't worry about the EC changing as the plants are going to uptake what they need if you keep it low enough they will be happy using osmosis to get big quick.

Don't get to caught up in the testing this & that runoff unless there is a big issue time is better spent trimming or managing the canopy.

Well the one getting 1.4 and giving out 1.6 is about right for mid-flower, when your feeding heavily. The one's running off at 2.6 are sat in a toxic environment though. Alarm bells should be keeping you awake at night. Keep sticking in that 1.4 until what comes out is in range. A typical differential for daily coco feeding is 20%. It's generally safer to run more to waste, narrowing the differential, but 20% is good commercially, where water costs money, and waste water processing costs even more.

On occasion, I miss the plants pass peak flower. So while 1.4 is still going in, the plants lower demand is leaving more food behind than the run-off quantity can remove. The EC may creep to 2.6 which is my upper alarm point. I never want it past 1.8 but it does pass this as it's how it tells me to drop the input level. 2.0 or 2.2 with the occasional 'oh shit' 2.6 upon seeing which, I will put 1.0 through them to get that 2.6 down to 1.6 again. It's simply quicker than flushing with 1.3 (my late flowering input, to get 1.4-1.5 runoff)

Rick why do you use canna aqua instead of coco instead of their coco feed? I’m all about the flavour so if gives better flavour then I’m all ears ...

Canna coco is a 2 part veg and bloom feed,, separation of bloom and flower feed give the ability to tailor your npk ratios,, i also find aqua has the best quality of things like red phosphorus too,, so I consider it the most versatile and best quality nutrition on the market (that I know of)
