Fitting an Reverse Osmosis machine this weekend and wanted to see if there were any other coco growers using RO water and what i need to do different than before.

Use a coco specific nute for RO, or use Calmag.
Canna is designed for tap, CNS17 is for RO. There are others, but I can only comment on CNS. It seems to be all you really need.
I would also recommend inoculating the roots with mycos. I've also used Cannazym and noticed it dissolved dead roots in a few days. Seems like great stuff to me.

ro here 2 cycles with flora duos and calmag
ro with maxibloom with this current cycle, every couple waterings I add some calmag.
You are good! Have fun

Calmag will be your best friend
True your gunna need some cal mag mate only one place in uk that sells it and you will need coco specific nutes they have extra cal and mag to compensate for the coco absorbing it
Not seen one made for ro in uk
If you want the link drop me a pm

I use it with GH Micro and bloom. you indeed need cal-mag with RO
However, If you mix 10~20% tap water, you might not have to use cal-mag.
but I would get it just in case.

Awesome info, thanks everyone.........i have also heard something along the lines of adding bicarb to stabilise the ph, anyone know anything about that?

Once you have added Bicarb and Cal-mag you have got most of the way back to your standard Tap water, just adding in Commercial products in place of the natural ones you removed.
Taking the Bicarbonates out removes the water's pH buffering ability, if instead you use a blend of Tap and RO you will have less or no problems and maybe do not even need the Cal-Mag. The RO is then working as a pH minus and EC reducer for you, without the attendant problems of pure RO.
Canna sell a range of individual Nutrients called "Mono" that you can use to amend their nutes.
RO is also meant to be the best thing to make ice Hash with

The calcium in Cal-Mag+ is from Calcium Nitrate, not Calcium Bicarbonate (Baking soda)
Calcium nitrate is a much smaller molecule that plants take up much easier.

Just wondering how much Cal-Mag everyone is using?

I used about 1-2 ml per g when I fed pbp, but none with cns at 15ml per g. I see some using 5-7mlthe calmag w/20ml of base and all kinds of additives. I may not have the largest yield, but theres no ca deficiency growing SD, a calmag whore

They are discussing bicarbs as ph up, not a source of cal.

bump** i wanna know how much calmag people are using with their coco-specific nutes and r/o water.
which calmag+ is everyone using?

Botanicare cal-mag plus and AN ph down concentrate. RO water is 7.0 pH and has to be lowered plus i use the GH or AN 3 part base nutes. read the labels as much of the trace elements are included. i add the cal-mag plus with iron as the plant calls for it @ 2.5ml per gallon. with a little sulphur you cover the primary, secondary and most of the trace needed for a great grow.
i also use PRO MIX HP which is an organic/soilless medium
www.premierhort.com i was allowed to post this earlier; read the whole website as this is = Coco Coir

always use RO water with cal-mag in hydro medium like coco coir. tap water is too sensitive for the medium
I have done head recipe with botanicare cal/mg at 2ml sometimes 3ml a gallon.
I have done flora duo, straight and tried adding 1ml a gallon.
the thing if interested, you need to keep track of your Ca / Mg going in. And modify from there if you are having problems.

id assume this would be based on what was in your tap to start with. my tap in the city jumped from 70 to 210ppm in the last 6months. i dont know why but id assume at this point im better off using calmag+ and r/o.
on my most recent set of clones, i started using the ro/calmag and things seemed to be going great under the t-5 my mix at that point was:
canna a+b 10/ml gallon (coco)
calmag+ 2/ml gal
rhizo 2/ml gal
cannazyme 8/ml gal
drip clean .4/ml gal
-this gives me a ph of about 5.45 so i use
silca (agricultural organics) as ph up
ph of 5.8ish
once the plants went under the 1000k and had been up potted from 16oz containers to 7"x7" pots, things slowed down after a couple days and i started noticing deficiencies and i was having ph issues in the root zone.
after measuring each plants run off and making notes and which plants had high ph or high ppm's building up.
i gave all plants the appropriate flush and started feeding as follows.
canna a+b 8ml gal (coco)
calmag 5-6ml gal
rhizo 2ml gal
drip clean .4ml gal
things seem to be doing a lot better and i should also note:
after the initial flush, my coco was wet but not rooted so rather than feed pots that need to dry a bit to promote the root growth,
i did 3 foliar feedings to help green things up
1st night foliar : epsom salt 1/2 tsp/per gal
2nd night foliar: rhizo 5ml/gal
3rd night foliar : calmag 5ml per gal
these foliar feeds really seemed to help and the new feed schedule seems to be doing the trick!
id love to hear from more people who are in coco who are using r/o and calmag+
how much calmag+/gal is the question
