Need help with crinum natans

[Bhavik]

So I have had this plant in my tank for a while maybe a month or so and it was nice and green for a couple of days but I then started adding liquid carbon and the leaves have now started to turn brownish or so.
Since then I have stopped adding the carbon.
I was adding lush max with the carbon.

Could you tell me why it is? Is it just melt? And should I carry on dosing or no?

There are 2 small leaves that I can see growing atm

Crinum is usually not damaged by standard dose of liquid carbon..........but it certainly does not need it either. Personally I would go without.
The leaves could die due to acclimatisation to life submerse - newest leaves will then grow out adapted and healthy.
A fertiliser right under the plant (=root capsule) often promote growth of Crinum.

But would if be alright to use about max of 5ml for a 200L tank?
I'm thinking of starting of with 3ml. I want to dose as I have new plants I and I want them to grow in an spreads and also will help the crinum grow quicker as well

I'm pretty sure that it was grow in the water but not sure sure.

I dose Lush max everyday and I put in a root tab during a water change

Should I cut the leaves of or leave them be for now?
