Brazilian pennywort browning leaves

[PremierFantasy88]

I've had this (what was sold to me as) Brazilian Pennywort in my tank as a floater for roughly 4/5 weeks now

No Co2
Dosing easy life profito once p/w
Low(ish) light tank (Aquasky LED) as kept on a relatively dim output for most of the day due to the fish I keep

Within the past week I have noticed that a lot of the leaves are turning brown. Any idea what this is and how to remedy?

Any advice appreciated

Are you able to remove the brown by carefully rubbing the leaves? It looks suspiciously like diatoms

It may not be the cause of your current issue, which as @plantnoobdude @Hufsa says, looks like diatoms, but EasyLife Profito contains no nitrate or phosphate, two of the essential macro nutrients for plant growth and health.

I would suggest switching to a comprehensive fertilizer such as TNC Complete or APT EI (EI version doesn't have to be dosed at EI levels, its just more concentrated so better value).

A third vote for Diatoms. Have you got any Bladder or Ramshorn Snails in your tank? These will get rid of Diatoms and are self regulating as far as numbers. A balance will eventually be achieved between amount of available food and snail population.
My Diatoms before snails.
My Diatoms 4 days after Snails

Clearly not enough morning caffeine! Now amended to avoid the wrath of @Hufsa 😱

@Hufsa yeah it easily comes off if rubbed gently

@Wookii will look into changing the profito, thanks

@The grumpy one I've only got assassin snails in there currently but will also look into this

Thank you for all the advice much appreciated

Haha sorry.. Matthew Kelly was a presenter of a show called "Stars in their eyes." People would transform themselves into their favourite singer, but before they dissapeard behind a screen they would announce who they were going to become by saying "And tonight Matthew I'm going to be..."

I wondered if you'd ask that. It was a 90's talent show called 'Stars In Their Eye's'. After an introductory chat with host "Matthew" Kelly the contestant would then say "Tonight Matthew, I'm going to be . . ." and they'd then quote the name of the singing star they'd impersonate before disappearing in a plume of smoke, and remerging dressed as their chosen star before singing a ditty:
