Bulb Configuration

What type of plants do you have?

@justin0com If you take some pictures, a long shot of the tank and some of individual plants you will probably get them identified and an answer to the original question as well

Here are the plants I have.

GREEN SPADE LEAF,
AMAZON SWORDS,
BORNEO SWORDS,
MALAYAN SWORDS,
HILL RADICAN SWORDS,
BORNEO FERN,
UMBRELLA FERN,
JAVA FERN,
INDIAN FERN,
ELODEA DENSA

There are a few more species in there but can not find there names.

I forgot to mention I root tabbed it and the substrate is 2-3mm gravel. Some plants I can not name are doing well. I have had an issue with bba and got true SAE fish which took care Of that a year ago. The t8 bulbs are on for 8 hours and the t5ho lights are on for 4 hours on/off over 6 Different times on the same 8 hours to simulate shade and direct sunlight as the t5ho bulbs are bright and they make the green stand right out.

Hope this helps.

What are your water parameters? Hardness, pH, nitrates? And in what way are your plants not thriving? Are they all suffering the same symptoms, or a variety? What size is your tank and how well stocked is it with fish?

As @Matt  said, photos would be great.

I'm not sure about your other sword plants, but Amazons need a lot of nitrates (or nitrogen in other forms). I have a heavily planted tank, but struggle to keep Amazon swords healthy because I have tap water with very low nitrates.

Java fern, however has a low demand for nitrogen, and is slow growing. So I would expect those two plants to have different issues.

The website coynie09 linked is really helpful. Not only can it help identify why you might have algae (for example I currently have pretty much every one that has "low nutrients" as a cause), it can also help identify why your plants are failing.

Have you heard about lighting regimes that include a siesta? You mentioned that your lights are on a pattern that effects the lighting levels, but you don't mention if they have a period during the day when they are off. I am a strong proponent of having a lighting siesta. I have found that for my tank 4-5 hours with the lights off in the middle of the day works really well.
