cal-mag(GH) vs Epsom salt for magnesium def

[tharoomman]

Title says all.

I got a bag of rock salt from a garden store but I will order some GH calmag online if it is really that much better.

Just don't have a lot of extra money so I don't wanna buy if I can get by with what I got.

epsom salt if you only have a Mg defic. if you have both calcium and magnesium defic, then cal/mg is better.

rock salt

is not epsom salt. FYI.

that doesn't look like a Mg defic.

could be calcium defic. you in soil? hydro? what is pH?

seeing that pic, i think cal/mg would be better.
