I think the batch I bought was grown emersed. So consequently, the lower leaves distorted and dropped off after a month.

I have no luck with this plant. It grows very slowly. I've read that it's easy to care for and fast growing so it's basically my fault..

here's my params.
CO2: 30PPM
Lights: 2.5 WPG
NO3: 30ppm
PO4: 4ppm
K: 1/4 teaspoon every other day.
trace: a cap full every other day.

I've read it likes a lean N.. (5ppm)...

29 gallon tank... THe only thing I can think of is my excess in nutrients...
I'll just take what's left and put it in my natural planted nano tank. Let's see what happens.

Ludwigia problem....

I always have problem wit my ludwigia, crinckle leaves, slow growth.

This is my parameter today an they now growing red and healty.

PH=6.9
kH=20mg/l
Gh=180 mg/l (to High)
Ca= 40 mg/l
Mg= 19.5 Mg/l (to high)
NO3= 3 mg/l (going up)
PO4= .25 mg/l (going up)
K= moderate dosing
fe(trace= .4 mg/l

I think a some factors for this result:
I lower my nitrate 20 to 3-5 (some people think that high nitrate is responsable for bad calcium intake (distort leaves)

To much potassium can block calcium intake
see:http://fins.actwin.com/aquatic-plants/month.200401/msg00585.html

Personnally I find your concentrations high...

I'm with you.
I think it's too high too. I'll have to lower the NO3 & PO4 slowly.. I remembered lowering it with a 50% water change and got an algae out break.

Well, good to know I'm not alone.
