toEpsomsalt: 0,4g/l (+39.5 Mg, +53 S)
Then, scratching the organic Biobizz ActiVera, as it seems I can use the Humiron in the preprepared stock-solution:"LOW NPK" formulae: (in mg/l)

^^ minus this, instead add:Biobizz ActiVera: 1ml/l (+3.5 Fe, +0.3 Mn, +0.2 B, +0.07 Zn, +0.03 Cu)
That looks much better… maybe a touch more mag sulfate. I think K is fine there.Then, scratching the organic Biobizz ActiVera, as it seems I can use the Humiron in the preprepared stock-solution:
^^ minus this, instead add:
Humiron 2.5g/50l barrel = +2.8 Fe, +8 K, and +2.5 N & S.
I have zero information available on the nature of that N....
Just realize I have a calculation-error in the above total-N by -5,9, will be corrected here:

Alright, in that case I revert the previous Epsom-throttle and up by 25% again.That looks much better… maybe a touch more mag sulfate. I think K is fine there.
Dexteose and L aminos from my understanding are a couple you may want to look at but i do t know enough to say anything definitive on them.Alright, in that case I revert the previous Epsom-throttle and up by 25% again.
And I think I throw Biobizz Topmax out, too, because, the traces mix can do its job on micros and it's best to be as simplistic as possible for starters. Later stuff can still be added.
I'm actually wondering now about sugars & aminos in cocos....

I'm having a product called "Siapton" but the exact composition isn't given. Just gonna have to try it out.Dexteose and L aminos from my understanding are a couple you may want to look at but i do t know enough to say anything definitive on them.
Most come prewashed and buffered these days. The CEC is much lower so since i use a high fertigation and low volume schedule the stability of nutrients is almost rock solid.@Aqua Man
There's one thing I'm currently debating with a fellow cocos grower:
How much Ca will the coco "steal", and how much K will be released?
I'm having a number of studies and online sources, but some of the info is in conflict.
It boils down to - how quickly does coco decompose; how much new cation-exchange-sites are newgenerated (which would bind Ca for a K release)?
And - if nute companies released special "for coco" lines higher in Ca but lower K because they want them to work in unbuffered coco (or less optimal buffered coco) as well?
Because, as I see it, and I take this data from studied, the washing and buffering greatly influences the amount of available Na, Cl, K, Ca & Mg in the substrat.
I use cyco coco lite with canna classic nutes and coco steals fa ca.and im under leds only feeding up to 570-580 max.one feed a day..work that out lol..@Aqua Man

Quality of coco is key as you say. I use canna coco as its prewashed, buffered and certified pest free.
But to answer in short you dont need anymore Ca and dont need to worry about K and Na release if you are feeding often enough with adequate runoff. As each feed is a slight reset to the media.
My coco was done in 1 gal pots feeding as much as 250ml 14x a day over the light cycle and once over night as transpiration rates are very low absent of light.
I did a thread here that explains how i do it.
HOW TO WATER COCO FOR BEST RESULTS.
Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...www.thcfarmer.com
So my intention is to run big pots -24l-, and manually feed, and this can't be done more often than 1, or maybe, twice, a day.I use cyco lite with canna classic nutes and coco steals fa ca.and im under leds only feeding up to 570-580 max.one feed a day..work that out lol..
In 5 gal id go 50/50 coco perlite and feed a litre per event. In that size pot you will likel range from once every 3 days to 2-3 times a day at peak if following the runoff I describe the n that threadSo my intention is to run big pots -24l-, and manually feed, and this can't be done more often than 1, or maybe, twice, a day.
So it's more like a peat-perlite setup but using cocos for medium, lower pH and mineralic salts, drain to waste.
I'd expect I have to feed way higher, starting from maybe EC 1.8 and drain more (30%) to get rid of the old nute solution...
