Hi Jarema Malek,

Looking at your pictures I see a few things. In the first picture chlorosis (yellowing) with wavy leaf margins and some 'puckering' of the leaves. In the second picture also chlorosis with 'leaf tip hooking' downward. Your dGH may be 20 but the leaves in the first picture would suggest a magnesium deficiency and the leaves in the second picture a calcium deficiency; the "leaf tip hooking downward" is a common symptom of a Ca deficiency.. Although you may have Ca and Mg in your water it may not be in a form that the plants can utilize. Try adding sufficient GH Booster (Seachem Equilbrium) to increase your hardness 2.0 dGH. If you use Seachem Equilibrium that would be 3 teaspoons per 10 U.S. gallons. Seachem Equilibrium contains, Ca, Mg, K, and a little Fe along with some micronutrients. Watch your new growth, if increasing the available Ca and Mg you should see the new leaves come in much better. It is unlikely the older leaves will change much.

Hi Jarema Malek,

We don't have that product in the United States, but what I found online about is was:
"Vigorous plant growth, no deficiency symptoms thanks to minerals such as iron, potassium and other trace elements" I could find no details as the the amounts or the "other trace elements".
