Tank Balancing Question

[Elyse]

I am currently in the process of trying to balance my 75 gallon aquarium. The ludwigia broadleaf looks a little yellow but I'm terrible at judging what deficiency plants might have. Nitrates tend to float between 10-25 and iron tends to be low but every time I dose iron hair algae starts growing. Can people take a look at these photos and give suggestions and possible nutrient deficiencies?

When I read that I remembered what my sister, who used to own a tree nursery, would say when people asked why their terrestrial plant leaves were turning yellow.  She'd say "It's probably either not enough water, too much water, not enough fertilizer, or too much fertilizer."

At least in your case we can rule out the first two.

Do you dose fertilizer?

I use seachem fertilizers…

Flourish 2 times a week, iron 1-2x per week, potassium 1x per week, trace elements 1x per week, and nitrogen 2x per week

I think everything looks okay. That yellow cast is from the light for sure.
