But all of this doesnt really explain what i first asked. The spot on the leaves i've put at the very start are not a CAL/MAG deficiencie according to my experience.

Mag deficiencies can take up to two weeks to show. They are slow in showing and clearing up.
You should do a foliage spray OR add it to your res, not both if I am reading this right.
GH calimagic has the lowest N content of the available calmags, thats why most of us use it in our rdwc shits. Its not huge in mag though thats why I use that + epsom.


I like this chart.
