@JoshP12 I don't think Co2 is the issue here, none of those plants pictured even need Co2 injection to thrive, aside from the s repens he mentioned. IMO this is much more likely a nutrient issue, judging from the yellowing and pinholes present in the leaves.
@tyler138 I've found the pre-made fertilisers like Tropica or TNC at their recommended doses just doesn't provide enough in a heavily planted tank, especially if you're using injected Co2. I was required to dose way over the recommended levels to meet the sufficient nutrient levels I required, and it just wasn't very cost effective. Have you thought about making your own fertilizers with dry salts? It's cheap, easy and there are even calculators on ukaps to help figure out what levels your aquarium needs. My aquariums have been thriving since I've been making my own ferts, and it's sooo much cheaper. Also, some of your plants might benefit from root tabs if you could get them.
