Calcium

Just my $0.02,...
But what is a good quick fix, is giving your plants a foliar spray of fulvic acid or kelp if you have.
It won't hurt the plant by any means as it is organic, yet stimulates the plant to better process the moment of unbalance.

I love fulvic spray. Probably should do it more. As far as kelp goes they get a lot of kelp teas. Do I soak my kelp in water for an hour or 12 hours etc. Then strain? I may do a fulvic, calmag, kelp spray tomorrow.
In 1 litre water: 1 ml fulvic? 1 ml calmag? 1 Tbs kelp soaked and strained? More? less?

Definitely foliar prays will help fix the issue much quicker, but not sure to what extent it can prevent the issue. Calcium is not mobile within the plant

 

[Builder0101]

Understood. I was saying/asking if it is a LO then a spray would be a short term way to address the issue.

I added a tsp of fresh aloe. Put that in a blender on low with the kelp. Gonna strain it and add it to the spray bottle with 1/4 tsp fulvic (recommended dose on bottle) 1.5 ml calmag. 1 litre H2O. 1 drop thieves dish soap which is all natural essential oils based soap.

If you have a wetting agent like Yucca to mix in to your foliar mix.( EDIT: just read your post about the soap,)
That just makes the leaves have better absorption.
The idea of the foliar is to give the plant a little stimulation to process whatever is at the roots a little easier.
15% of the plants nutritional needs could be done by foliar spray alone.
What ever else is needed will be processed through the roots. ( don't tell the plants we know this!)

Its kinna like buying time to fix the situation with a better balanced feed via the roots.

Also it is supposed to help the plant return carbs down to the microbes. Symbiosis.

Side note my dehu is outside my tent in the lung room; therefore, I need to crank up (or down depending on perspective) the dehu when foliar spraying lights out.

Never foliar at lights out, That will promote PM and other molds. You obviously have a problem and based on what I am reading you have got your nutrients way out of balance. Maybe too much of something. How are you testing the PH in the root zone? That chart is a soil chart and since this is Coco this is a hydro grow and doing hydro "Organic" is an uphill battle to start with.

Do you fertigate to 20% run-off every day?

I would first test the root zone PH with a GOOD meter (Accurate 8 or BlueLab for Coco probe) and then add an immediately available Cal-Mag supplement. You may need to resort to a good flush and reset with balanced nutrients plus extra Cal-mag for the coco.

@GeorgeCloney I have grown Organic in soil in the past. I grow hydro now and use salts. I think it is too complicated to try to grow organic hydro.
