Half of my TC S.Repens have died and these have been surviving and thriving since I added CO2. Just recently noticed the plants are curling and partially turning brown in some spots.
Is this diatoms? I tried removing it to no avail. I've been dosing Seachem Flourish 2 times a week and I have Tropica Specialised Nutrition coming on Monday.

Another Picture

Pic would help. I've got a ton of diatoms on my s repens a my set up is new I'm not too concerned, the leaves aren't turning brown per se in Maine but look like they have brown dust on them. Curling and actual leaf turning brown could be a reaction to changes in parameters/ ferts. Is the new growth coming in okay?

*Edit- just saw pic. Looks fine to me, probably just diatoms. If this is a relatively new set up just keep testing and taking note of changes. You could possibly dial back length of photoperiod/ intensity of par while getting a handle on it. Perfectly normal, though.... Unless it smells fishy...

Just added one ^ I did have some dust which I believe was diatoms. They removed very easy and I'm going to be purchasing some Otocinclus soon to help with that. This seems like the leaves are actually turning brown.

Ah, I see what you're talking about now. Your new growth looks good, the old growth looks a little worse for wear. You could remove a few of the more harshly damaged ones, it doesn't look bad to be at all though.

Yeah I might just dose some Tropica ferts and see if they come back
