Hello forums

I'm having trouble with identifying what kind of defeciency these ludwigia are having, my tank has been running for a week, all the other plants are doing fine.


The tank is 30 litres
Here are my dosings (Lean)

4ppm Potassium K (12ppm per week)
3ppm Nitrates NO³ (9ppm per week)
1ppm Phosphates PO⁴ (3ppm per week)
1ppm Magnesium Mg (3ppm per week)

And .1ppm of Fe (.3ppm per week)

My CO2 is running at 4bps ; my PAR reads at 90 on surface level ; Goes for 6 hours a day.

As you can see, these Ludwigia Glandulosas (red) have grey tint in their inner leave veins, I'm very confuse to what defeciency these plants have.

and as for the Ludwigia cuba (green), some of the new grown leaves are curling down , others has stems growing sideways. Could it mean it's adapting to the new environment?

Thanks, Kevin

Both plants appear to be emersed grown, adapting to submerged will take some time.

Is Fe contained in a micro mix?

What is PAR at substrate?

What about other micronutrients?
There is a list of them, Fe is just one of many!
Hey, thanks for replying

For trace source, I use seachem flourish trace, and use accordingly to my tank volume, which comes to my question, do you have any experience with seachem products?, I'd like to try seachem system but a bit confused about what of their products to use.
