Problem with anubia

[Tarcisio Augusto]

Hi,

There's something happening with my anubia's leaves. The new ones are getting smaller. Maybe, it could be a nutrient deficiency, heavy metal toxicity or is it connected with something else? Here is a pic:



Thanks

I get this in tanks with low light, no CO2 injection and minimal fertilisation/rare water changes. Grown in high light, well fertilised tanks, normal sized leaves will develop. What is your setup like?

Hi Budak,

setup:

0.6w/L
co2 injection
water change:25% every week, but no liquid fertilization.

It could be somekind of nutrient deficiency?

Thanks

Have you measured the pH and KH? What are the values?

Lack of CO2 and NO3 may cause new leaves to turn up smaller.
