How to revive anubias nana?

Hey all! I set up my first tank about two weeks ago. I currently have 2 anubias nana, 2 anubias nana petites and 2 java fern in my tank. I have a huge piece of driftwood with java moss on it as well. There's one nana (not petite) that is suffering bad, and I'm not entirely sure why. It has holes in its leaves and the old leaves are turning yellow. I figured it was a potassium deficiency so I've been dosing some seachem flourish potassium in the tank for the past 2 days. Still waiting to see if it helps.

Do you know why one plant isn't doing well but all the others are fine? At first, I thought maybe the plant was receiving too much light so I bumped my light down 2 settings dimmer and for 8 hours rather than 12 hours. That was before the leaves starting turning yellow. Now the plant looks like it might have new growth but I'm not entirely sure what new growth looks like compared to a super small dead leaf lol. I will attach a picture later today.

Do I need to trim off the yellowed leaves?

 

I’m not good with plants what so ever lol but this may help Deficiency List for Plants | Aquarium Plants Forum | 168302

 

Could be a deficiency of some sort as you say, although anubias are relatively undemanding when it comes to nutrients. Could also be some initial die-off after being introduced to a new environment. Pictures of the plant will definitely help though.

In my experience, anubias is probably the hardiest plant and easiest to care for. I’ve been trying for years and still haven’t managed to kill one!

I was thinking it might be due to moving to a new environment, but all the other plants look a lot better than this poor guy.

 

I agree with others. Your plant is most likely transitioning. Plants have variation even within species. So, it's not uncommon for one plant to struggle more with transitioning than another.

I would remove the yellow, dying leaves. They won't come back, but they will decay eventually.

In my experience, it isn't high light that anubias struggle with...at least not directly. Anubias just don't protect themselves from algae very well. So, a high light environment is more likely to see your anubias covered with algae.

Yeah I haven't seen any algae yet, so that's a good sign. It's a new tank and is still cycling so hopefully it'll start growing more soon
