And there is a tidal motion in every glass of water. Next you'll say the motion of that tide adds O2. You're a troll & I'm done with you.
Over watering? Nutrient lock out? Pics included.

adios!
don't let the door hit ya' where the good lord split ya'.
p.s. if you have a DO meter and a camera, i'll put some cash that i'm right about a watering can.

Hey now, nobody puts air stones in lakes and ponds, but fish seen to survive there just fine...

I know you are trolling and I said I was done here. But, I figured if you are serious maybe you would take this info better from a company that sells coco.
"One of the biggest issues with coco is watering practices. Coco is a sponge, and like a sponge, when squeezed water comes out, but not all the water. The sponge will remain damp and coco can still appear wet without having enough available water to give to the plant. Constantly watering coco results in over-watering. When using coco, there is a need to water at a minimum of 50% dry. Sometimes 70% dry might be better especially during the first weeks, when most roots are formed. After all, the roots also need oxygen and where there is water there is no air. A sophisticated and reliable method to measure the plant available water in the coco substrate is a tensiometer (pictures 3 and 4). It is a device that determines the water potential in a substrate, effectively the force needed to release the water from the substrate. This ‘force’ is minimal in a water saturated substrate and maximal when the substrate is completely dry. " - Canna Coco

again... optimal moisture in any medium is never full saturation. peace bb.

from cocoforcannabis.com:: 2 sides to every coin.
The Air to Water Ratio
Plant roots require both oxygen and water. If the roots are starved of oxygen, they will turn brown and die. Soil based growing media become oxygen depleted when they are saturated with water. This means that the roots are unable to get enough air for some time after each watering. Growers need to wait for soil to dry out before watering again because otherwise the roots will not get enough oxygen and they will die.
One of the miraculous things about coco coir, especially when its mixed with perlite, is that it is nearly impossible to over-water it. Unlike soil, coco maintains sufficient oxygen in the root zone even when it is at field capacity (completely saturated with water). This is due to the physical shape and characteristics of the coco fibers which retain air even when the media is saturated with water. As a result, we can keep the coco wet and not worry that we are drowning the plant roots. Indeed, in coco, when the media is wet, the air to water ratio is ideal.
Coco is Not Soil
The fact that coco retains enough oxygen when it is saturated largely eliminates the risk of over-watering. Because of this, coco is far easier to manage for new growers than many assume. In soil, it takes experience to know when to water. Plants in soil are moving between being oxygen starved after a watering and being water deprived as the soil dries between events. In coco, on the other hand, plants never need to suffer, and growers don’t need to worry about over-watering. All you need to do is water frequently to maintain the perfect ratio of air to water all the time.

Hey, problems returned, grower in charge of that room doesn't know what to do. this is what they look like most of the day now. Could this be from too much light?

That's what keeps coming up but he was only watering every few days, he's was giving them way too much water each time but I didn't think that would matter, it'll soak up what it can and drain the rest right? Just a huge waste of nutrients lol. Drain to waste set up

I am not a coco grower, but I would think watering at high ppm, and less frequently, would be a recipe for salt buildup in the medium.
Giving it a lot of water/getting a lot of runoff is probably fine, as long as it has a way to drain out each time

There's just almost no way its from watering too frequently, 3 gal fabric pots watered maybe every 4 or 5 days. Maybe it's the humidity kept at 65%-70% in conjunction with the watering? I'm at a loss here

Again, not a coco grower here, but there are people doing 4, 5, 6 feeds per day in coco. The general consensus I've noticed is coco should be watered at least daily to runoff, never allowed to dry out because doing so can lead to salt buildup.

those fabric pots have become a nute sponge and i'm sure are loaded with a really high EC
water coco daily to runoff

As long as you don't go over the field capacity then ya it's practically impossible to drown them in coco after they root. Going over FC would be something like sinking the whole pot in a bigger bucket of stagnant water, or hosing it 24/7 to the point of being flooded (faster than it could drain) or something.
Ebb and flow with coco is interesting.. because as the water level moves down, it does in fact create a special vacuum like layer within the medium that pulls in more oxygen from the top as it drain. Or at least thats what I heard years ago. Haven't done a lot of F&D though.. If true, I would imagine it's unlike just top feeding or hand watering the coco through drippers or hose, which you are trying to fine tune the cycles for best overall air\water ratio..
