I would add MgSo4 anyway. It cant really hurt. I belive the PPS-Pro home page has measurements for it.

I said what you can do to lower your kH. It doesn't mean you should do it. The kH range I mentioned is what I consider best for plants based on my own observation. It also doesn't mean your plants cannot grow in kH 8

My plants grew fine in higher kH and gH than yours. Some of them like Vallisneria use kH as a source of Carbon and some do not like it at all as it will limit CO2. Tonina on the other hand prefers soft water with lots of CO2.

There's no short answer to all plants. You will need at some point to experiment and learn which are the values that yield the expected results.

Another question only way to know my calcium and magnesium is with a tester right?

How do i add magnesium or calcium to my aquarium?

Using pfertz [m], [n], [p] & [k]
Dosing flourish iron, and flourish excel aswell.
Mg++ deficiency is a little more common than many assume.

It's one of two things: veining of leaves, common in Swords and in Anumbias, but few other species.

The other is a general color loss of greens and slower limited rate of growth.

Adding MgSO4 back will restore the green color very fast(it's the central atom in Chl a, b etc, other wise the molecule is grey in color). and should restore the veining issue in a few days.

I've had everything from 0.3 ppm in tap up to about 50ppm of Mg. In dense tanks where folks do not add any known source of Mg, it can and does happen, most often when folks assume their GH is a nice balanced ratio of Mg and Ca, sometimes it is all Ca++, but extremely rarely, it might be mostly Mg, I've never seen a tap like that yet but perhaps one does exists somewhere. GH measures both Ca and Mg, not both.
If you dose a known source of GH, say GH booster, which is about a 1:4 Mg/Ca, then you know you will not be limiting.

Or most add MgSO4 to their CMS mix for traces.

Plant, your right. It is magnesium deficiency!
Where exactly can i find some MgS04
Seachem discuss buffer? Replenish? Or equilbrium?

Epsom Salt is MgSo4. You can get it at any Walmart or Pharmacy.

Get yourself some Seachem Equilibrium and you'll be all set. Here is a pic I just took for you....

GH booster is the generic salt mix of Seachem Eq, it was modeled after SeaChem Eq.
