Echninodorus Argentinesis, E.barthii and Crypt Usteriana not growing

Even so, the situation is rather interesting in two aspects:
(1) The substrate is supposed to be a rich source of readily available nutrients. Apparently this does not solve all situations.
(2) I've got rather clumsy results with my Echinodoruses in soft acidic water. Now it seems that basic-alkaline water (with CO2 support) is not the remedy either.

Well this is a bit different specie, Echinodorus Argentinesis. The regular Bleheri grows like a weed.

Crypt Usteriana is another slow grower!
Not sure what i can add to help increase growth for these plants!
Increase fertilizer?
What colour is the drop checker?

Lime Green, a little bit yellowish. So for now only waiting. I will wait 3 more months, lets see if it will help. If not I will put something other instead of it.

What is the tap water Nitrate ppm?
Click to expand...
According to drop tests 0. In aquarium after fertilizer about 40 ppm.
Also maybe I need more light. I have 2 Zetlight Lancia-2 leds. Today I will add to the background one more Dennerle Trocal Led 160sm which has more lummens. Maybe it will help.

@GHNelson This one is actually E. palifolius mislabeled as E. argentinensis synonym of E. grandiflorus.
www.flowgrow.de

Echinodorus palifolius

Echinodorus palaefolius is often offered in trade, however, it is not often sold under its real name. A rather acuminately-tipped form quite similar to E. subalatus (fig. 3-5) is called "E. argentinensis" in trade, however, it has...
