Zosterifolia : Leaves have dark patches and some transparent

[alex crouvier]

I just planted some H. Zosterifolia last weekend around the time I injected
2 bubbles/sec of CO2
The rest of the older plant residents: E. Stelata & Hygro Difformis are
doing fine. My Stelata actually
bushes out at the tip, looking like a beautiful ancient plant. My Difformis
leaves turn vibrant dark green
after I dosed the tank with Tetra Flora Pride and Seachem Potassium. Now my
Zosterifolia is not doing
very well. The older leaves seem have dark line patches towards the tip.
Some of them are transparent
with blackening. Zosterifolia can withstand up to 28C which my tank is at
daily. I wonder what else is missing to
stop the darkening of the leaves. Or is this a case of CO2 shock where the
mobile nutrients are sucked up
to the new leaves?
gH >6dH
kH approx 3
pH 6.6
Lighting at 3.5 watts/gallon

There are about 20-22 Tetras, Lampeye killies and Rasbora Espei, 4
Corys and a Pearl Gourami in this 15 gallon tank.

Since I add CO2 it is very difficult for me to keep fast growing plants
like H. zosterifolia...

After adding too much K to prevent these black patches/white leaves/meltings
ala Crypto
I'm trying now with more Fe without much success.
Cleaning the pump produces a melting even when adding extra doses of traces
just after the cleaning...

PO4 is 0.5
K 90
NO3 between 7 and 80 depending of the test (let say 25)

Best regards,

Philippe

Also

As some of broken stems are floating waiting for roots
some are whitish with leaves whithout tissues other rather fine...
I think they change of place during the day or if they are static
from what can the growth depend :

Distance to CO2 reactor
Distance to water from filter
Type of lamp
