following tom's advice I stopped with the reconstitution of RO water with sera mineral salt and just used caso4, mgso4, k2so4, nahco3.
but then I looked at the composition of the hoagland solution (wikipedia) and wondered a couple of things:
* N 210 ppm
* K 235 ppm
* Ca 200 ppm
* P 31 ppm
* S 64 ppm
* Mg 48 ppm
* B 0.5 ppm
* Fe 1 to 5 ppm
* Mn 0.5 ppm
* Zn 0.05 ppm
* Cu 0.02 ppm
* Mo 0.01 ppm
there is no Cl or Na. not necessary?
If I look at the levels of the macro elements, I tend to see that in the aquaria levels (apart from N and P) are 5-10 times lower.
could/should this also be extrapolated to the micro elements?
If so, I could run into deficiencies for B, Mn, Zn, Cu, Mo. because you never reach these levels with TMG/flourish.
probably, this is why the CSM+B exists?
so taken together: would it be a good idea to add a bit of B, Mn, Zn, Cu, Mo to the RO water?
