anubias plants leaves turning yellow

Hi guys was wondering if i could get some input so i recently added a few anubias plants to my tank within the last month but the last week or so ive noticed some of the leaves have been turning yellow on a few plants. Ill try to give u as much detail as i can my nitrate levels are currently 10 ppm i have a 125 gallon tank my stock is 7 adult discus all around 5.5 to 6 inches 40 cardnial tetras 30 rummy nose tetras and 3 german blue rams my lights aren't really that strong two aquatic life edge leds i have them on 8 hrs a day i currently do 50 percent water changes 5 to 6 times a week I feed 3 to 4 times a day and im using seachem flourish for ferts i heard anubias don't need many fertilizers but im running into some kind of deficiency should i add some macro nutrients like pottasium or add nitrogen i just don't want to over do it with the fertilizer and cause more issues and alage just want a simple anubias set up maybe add iron anyway heres a pic of the leave i pulled off what do you guys think do i need to start adding the macro ferts or iron or what thanks id appeciate any feedback Attachment 116195Attachment 116196

Were the new Anubias grown emersed (not in water) or submersed? If there is any new growth, is it healthy?

- If they were grown emersed and only the old leaves are yellowing, then things are just running their course. Nothing to worry about.

- If they were grown submersed, only the new leaves are yellowing, and the veins remain green, then they need iron.

i believe they were grow emersed i bought them online ill have to check from the company i got them from but i believe they were emersed should i trim the yellow leaves off and i have been getting getting a new leaf like maybe once a week would you recommend adding any ferts or is the seachem flourish enough for the anubias plants or should i add in the macro fertilizers also thanks for the response

If there's only a few, clip them off close to the rhizome. A leaf a week is pretty good for a C02-less setup, so I'd hold off on the ferts.

ok i guess its not on every plant i get a new leaf a week i guess for the whole set up i get maybe two to 3 plants that grow a new leaf sorry i didn't explain in correctly but thanks for the help
