The reason for constant watering in coco isn’t for water its for oxygen

Look Out, excess or deficiency?

Here is my current grow - pics from a week ago. I will update later today. I use Cann as well but their Canna Coco A+B.
Just like a full on hydro dwc, the roots need water, oxygen and nutes.

U missed my point.
Just go to the nearest shop and ask for a complete foliar. Can even be one for tomatoes or other plants, and use as directed on the package. You just need to check that it contains at least the basics, and ofc the Fe. Most don't need ph correction, and is ok to use distilled water.
I don't belive you should water daily in 12 liter pots, especially with small plants, but for sure you need to water before it starts to dry out more than 1-2 cm deep, and also way more often than in soil. With bigger plants they will for sure need the daily waterings down the road.

As in availability of oxygen?
Well whatever the reason my plant is perking up already, leaves aren't drooping anymore. Yeah for flushing!
Thank you guys
I am so glad and happy!
Now I understand that I should allways water with run off?
And the stressed plant with low ec and ph of 5.5

No.
Yes, roots need O2. But without water, nutes for growth (and light and proper temps and humidity) . . . ? It is a system and all parts of the system are critical.
The more often the fresh nute solution comes throught there, the more time the roots stay in the sweetspot. It's as simple as that. But you kinda need to make the plant agree with that, as in healthy plants in right size pot, to be able to water more often and make it count. As others said, it's a system, balance is all you need. And ofc you should know the basics for the method you are using, like the fact coco needs water more often and better to give enaugh for runoff every time.
Also, as a general rule, raise the EC gradually, if you start with the mindset 1.2 EC is mild, you are guaranteed to feed more than plants need. Unless you run your system to perfection and they show defs even then because of super high intense lighting, you should never go above 1.8-2 EC. For most grows, 1.4 to 1.7 EC (when at full dose) will keep plants more than happy.

I mix glycerin in with my foliar feeds. It pulls moisture out of the air and keeps the solution active on the leaf surface, makes the leaf shiny though.. Distilled or RO or Rainwater would be the best base water for it.

Thank you for that Info.
What amout of glycerin for 1l of water?
Does the glycerin coating on the leaf hindern the stomata in their job?
And I assume not spray on the flower.

Maybe 5mL per L. The light will break it down over about two weeks. It's quite biodegradable and harmless.
Glycerol
M.J. Wernke, in Encyclopedia of Toxicology (Third Edition), 2014Environmental Fate and Behavior
Glycerol is completely miscible with water. When exposed to moist air, it absorbs water (hydroscopic) as well as gasses such as hydrogen sulfide and sulfur dioxide. Glycerol has low volatility, with a vapor pressure of 0.000106 hPa at 25 °C; the calculated Henry’s law constant (maximum solubility) is 9.75E−6 Pa m3 mol−1. The calculated photodegradation half-life of glycerol in air is 6.8 h. Glycerol is readily biodegradable. When released to the environment, glycerol is distributed to water, with negligible amounts distributed in air, soil, or sediment. Based on a log Kow of −1.76, glycerol has a low bioaccumulation potential and is not expected to bioaccumulate.

I have just sprayed both ladies with a mix of
- horsetail extract (Schachtelhalm by Neudorff, lots of Silica, some MgO + sulfur)
and
- Rhizotonic (by Canna, fluvic acids and Bvitamins)
in destilled water.
Hope that is enough!
If deficiencies persist I will get Ferramin from Neudorff (an extract for foliar feeding with lots of Fe).
Will get glycerin tomorrow.
And my PH meter just died
Amazon can get the new one here in two days :/

Consider what it takes to move 5.8 ph H2O to 6.9 ph run-off.. The base numbers are not the end of the story.
It tells me that your coco is well over 7 ph by that result.
Though I don't do coco grows for numerous reasons.

Have now sprayed the plant twice with the Fe (+ some N).
Looking a little better, mid size fan leaves are getting more green, larger leaves still looking anemic.
Am going to flush again tonite:
Does it make sense to lower the ph of the water to say 5?
Since last flush the run off had ph 6.9 even though I watered with ph 5.8....
