It looks to me like you have hard water. The hygro plants look quite yellow, which is a result of a shortage of iron due to too much calcium and phosphorus in the water. I have very hard water, but my crypts and anubias thrive. The val plants I tried always faded away over time.
Four ideas:
1. if you want to grow more types of plants, including val, try using 75% reverse osmosis water
2. Fertilize with iron only
3. increase your light to 12 hours a day
4. Get some small algae eaters like bristlenose plecostomus.
Here is a planted tank with very hard water using the parameters above. I have four light fixtures on it, but use tap water and no CO2.
