Coco coir, remo nutrients and led.

Yup. Plenty runoff every feeding and 1.7-1.8 EC.

Yep im on top of it now ! Ec is at 2

Are you sure that sensor is calibrated for coco and not for soil or peat based potting soils. I would ditch the co2, lower ec, keep the containers they are plenty big enough. Keep the sensors but just use them as a guide not as your sole source of info on what is going on in the media. When you can keep them healthy thru a whole cycle over and over then add co2 , and try to crop steer if you think its necessary.

Hey brother , may i ask why u think its a good idea to ditch the co2 ? yep sensor is calibrated right , the ec now is at 2 . apart from the sensor im checking runoff ph ec and volume. Why am i asking about co2... cause without it i was hitting numbers pretty nice and all was dandy for few cycles ... but with co2 , i get these deficiencies so im wondering . iv been growing for 16 years now... but i'm new to cropsteering with LED and i kind of like it.... new learning curve and all..... next cycle i ll keep my co2 at "normal" levels... just a bit up... like 600 ppm cause my room is sealed. Thanks for the words and chiming in .
About the pots... yes i think they are ok size , but my mistake was that i vegged then to long in these pots... so i coudnt catch their drybacks... causing ec spikes in the media... and they were below what i would like for water content ... way below.
So next round... i ll do my veg in a smaller pot... and transplant then 3 to 5 days before flip... so i have room to steer then generatively for first 3 weeks without having then getting to fast of drybacks ... i definately think these huge drybacks... by huge i mean... from 45% WC to 7% ... I wanted then at 25% maximum , spiked the EC way more then i wanted....etc etc.... sorry for the bla bla bla

EC is way too high.

Yep i guess so eheh .

You just don't get it......do you?
This is someone else's thread......not yours.
The guy you quoted told you this wasn't the place to ask your question.
But yet, you had to ask him a quick one. WTF.

Pff .... dude didnt get it ....

Still too high. The reason your waste ph is so much lower than what you're putting in is because nutes are accumulating in your media.

 

[f.r]

But that would lead to his sensor picking up high EC within the media? he says it is at 2 within the media now?

Maybe I missed that, last I saw he said media EC was 6, and 2 going in.

I,ll lower that next feed im about to make another res , but yeah for sure its that low because of the nutes thats my 2 cents to... and also start when they stayed at verylow water content , taking that ec pretty high.... and u are rigth feed ec 2 now, ec inside the media 5-6 ... wich is ok acctually at this stage maybe better 4-5 .

But that would lead to his sensor picking up high EC within the media? he says it is at 2 within the media now?

Media Ec is a bit higher like i said .... feed ec now at 2 , i ll take it to 1.7 next feed.

I'v taken pwec like to 8 and they were loving it , but seen people going 10-15..

 

[Prawn Connery]

Thanks a quick one then as they’ve only been in these pots 4 days do you still think it’s a good idea to pot up yet?

Don't repot. You can continue to grow in those pots for at least another two weeks. You want your pots to be full of roots before you repot.

A good way to tell if a plant is really root-bound is that the lower leaves start to yellow, like a nitrogen deficiency (which is what it is) while the rest of the plant looks green and healthy. That's always a sign the plants have outgrown their pots. You should also be able to see roots coming out the bottom of the pot and winding around the outer egdes. The top of the coco will be very hard to press down on, as the pots will now be packed tight with roots instead of loose coco.

Try to to repot too much as it causes stress each time. And don't overwater when you first report becuase the roots need time to fill out the pot and in the mean time your coco will be wet and start to smother the root system. Water around the base of the plant and only rewater when you see the middle start to dry out. Do that for at least a few days to a week after reportting and then ater as usual, with at least 10% runoff each time.

Great thank you

Too many irrigation events IMO. I would guess that the EC of your substrate is very high because of all the feeds. Coco has a high CEC and will hold on to nutes.

I concur, I water every other day in 10 gal coco pots and by the time I feed they're still holding a good EC & PH.

you are hand watering the op is using drippers combined with a moisture sensor and pore water ec sensor using a technique called crop steering.
what ec feed and frequency you use for your watering cycle is not relavent compared to the op's.

if you are watering every other day with an ec of say 2.0ec its entirely possible that you would have a higher pwec than the op watering 6 times a day with 3.0ec.

He there , thanks for the inputs... i bet they are 10 gallons pot its quite a pot, here im at 1.5 gallons at the most , but like grobags says , im using drippers and cropsteering... its possible to go up to 10 ec feeding all the way tru with 2 / 2.5. thats what im trying to do at the moment... and i for sure there is many ways around it. Acctualy when u are feeding it multiple events along the day im trying to keep my EC down....

CROPSTEERING there is basically 2 ways of irrigating.
generative wich is going from maximum field capacity lets say 50% to something like 25% .... having long periods of dry back like 22 hours. getting ec to stack
vegetative wich is going from maximum field capacity 50% to something like 40 % max... small drybacks.... smaller ec swings... and lower ec across the board.
If u want to creep up or down your EC ...one would try to get there with irrigation strategies.... not so much changing ec.
Im not an expert... but thats is some of the guidance .

I disagree. I've grown in coco for 20 years and I've learned first-hand the more you water, the faster the growth. Coco is not soil - it is a hydroponic media and should really be treated as such. More watering events delivers more balanced nutrient solution, as well as delivering more oxygen to the roots. As long as you have good drainage, the system self-flushes and does not build up nutrient salts (apart from initial cation exchange, which can be addressed by pre-buffering with magnesium and calcium). Treat coco like a hydroponic medium and it will grow almost as fast as any other hydroponic solution. Treat it like soil, and you will have the same potential issues (salt build-up and nutrient imbalance) coupled with slower growth because you will never really know what's in it. EC doesn't tell you want types of salts are in solution, only that there is a higher or lower concentration.

I'm sorry, but what does that meme mean exactly? Are you talking about hand-watering? Because I'm talking about automatic irrigation in a run-to-waste system. You should try it if you haven't already – you will never go back to hand-watering coco again.

Coundt have said better myself... im with you on your toughts.... by experience u see when u pump those irrigation events plants blow up... and thats exacly what im trying to achive.... more oxigen , new and more balanced solution.... or i would just stick with soil and hand watering .What i look to in coco is exacly this...hydroponic results in a pot without all the troubles of hidroponic sistems, and not having to hand water... plus getting things to be more dialed each run.
Anyway... not trying to bash on hand watering or other growing practices.... its just not the road im driving into rigth now.... but hey , like i said.. i did notill for quite a while and loved it .

Thanks for the words Prawn....

 

[Prawn Connery]

No worries. Horses for courses. Just grow they way that suits you best but be aware that some techniques are more efficient than others if you put the time and effort into using them.

 

[PJ Diaz]

Crop steering in coco is extremely difficult due to the high CEC of the substrate. Good luck, but I'd stick to Grodan cubes if you are going to try crop steering. I'm not trying to be a dick, but it's pretty clear from the pics in the first post that it isn't working. You can argue all day long about how others have success and you can continue to push it, or you can try something different.

Well i guess i ll just have to try right , i wont argue ehehe ur not being a dick i respect that ... i will just do it . but i know it aint the easyest... but it aint rocket science with a proper sensor.

But for sure i ll be giving cubes a go to , they retain more water and less of a problem with the media.
And i didnt expect to be dialed in also in the first ones... but failures dont get me down.... not trying to be a dick also... its just how i am... i put myself into to it... i will go tru .

Have few friends doind nice at it already in coco... but for sure there is a lot of tweking to get there, nowing where one is mistaken also plays an important role. thats why we r here.... i wasnt into just posting pics... i like the challenge.... if u are up for a hand lets go .

PS : my veg and clones are dialed in the steering... and just by how im managing then and how they react makes me wanna be able to do it in flower also

 

[Roguedawg]

I suggested ditching co2 because you said you had healthy runs without it. If your in sealed room keep it.
I have noticed people mention doing drawbacks with coco and have been wondering how the hell can you without ec spike. Using the pot up timing maybe the best solution in coco. I would focus on keeping them healthy thru the whole cycle before you try to steer.
On the high ec, i only go over ec 2 when i first pot up because my coco is still charging up, i quickly go to 1.3 to 1.8 from then on.

kk, just thought he was like a few other people on here who have posted saying the op's ec is to high without maybe understanding the theory behind what the op is doing.
i was the same until i read up on it, i couldnt get my head round how you could run such high ec's but it turns out you can.

it might well be too high for his current strain and feeding schedule but there are people out there using this system feeding 4.0ec with a pwec of over 10 with perfectly happy plants.

there are so many different variables that effect what strength ec you can feed a plant ie,-

pot size, pot type.
medium used, coco/rockwool/soil ect.
system used, nft/dwc/flood&drain/drippers/hand water ect.
irrigation amounts, pattern and frequency.
root temp.
room temp.
nutrient profile.
humidity %.
co2 %.
light intensity.
light spectrum.
plant genetics.
