There are two options. One is to get new lighting, and select what is good for this situation. That's a topic in itself so I'll just mention it and move on.
Second option is to work with what you have (lighting). The plants in the photos are not all that bad frankly. The faster growing plants are having the most difficulty which is to be expected because they are higher light plants. The tiny holes in leaves is something I see and I know in my case it is due to light. Stay with what works. The Anubias and Java Fern and floating plants should be fine. Vallisneria does best not only with brighter light (it is fast growing) but also hardish water, I had both issues with my Vallisneria. Amazon sword plants would probably do well here, with a Flourish Tab. My tanks all have low to moderate lighting and I have had thriving sword plants for more than 25 years. What works I keep, what doesn't I forget.
I would dose Flourish Comprehensive Supplement once a week, the amount as recommended on the label. A second dose might help, but I doubt it because I do think light is likely the issue. And more ferts could mean algae problems. Don't know the light photoperiod now, but 7-8 hours might be best. I have found this to be the case when it comes to lighting being on the minimal side. Use a dimmer so it is consistent, helps fish as well as plants.
