The photo is blurred. You mean the bottom part of those plants? Give more information about your tank setup, lighting system and schedule, fertilization, CO2 supply... etc for diagnosis.

1. Details of your dimension, i.e. LxWxH
2. T5 8Wx2: That may not be enough for your tank. Let's have your dimension before we further discuss.
3. How long has your tank been set up? Anyway, you have almost 14-hr lighting and that's too much. Algae will burst and the plants cannot rest...
4. How many bubbles per sec do you have? I guess at least 1 bubble per sec is the minimum.
5. What filtration system you're using? Canisters? Or hang-on filter? What is the water flow rate?
6. How frequent do you change the water? And how much each time?

Just a few points to share:
1. Your tank is of 30l of water. Your lighting system is far below the standard for 陽草. At least, 30w of light is required.
2. The lighting schedule is too long for a new setup tank. You'd better start with 4 hours, and increase one hour each week until 8/9 hours. Otherwise, algae will burst.
3. You've got a bubble counter, haven't you? You need 1-2 bubbles per sec of CO2. The timing of CO2 supply should be sync with that of lighting.
4. Don't use hang-on filters. Buy a canister instead. Hang-on filters will greatly impact the CO2 level in the water which is not good for aquatic plants.
5. You should change the water at least once a week, and no more than 25% each time. BTW, how many fishes do you have? If there is many of them, you may change the water more frequently.

1. Yes, you need to change your lighting set. Consider Daz T8 15Wx2.
2. You have to change the hang-on filter. If you have to keep it, try to increase the CO2 input level, say 3-4 bubbles per sec. Keep an eye on how your fishes react. Just in case they suffocate.

Ching,

My tank is of same dimensions as yours (16"X10"x12"). I am using T5 8WX2 T5 only.
The lighting duration is normally 8 hours per day. I think is good enough.
Some guys think 1L water needs 1W light but I don't agree.
The main concern is whether the light can penetrate though the water tank.
I don't have much experience but would like to share with you before you decide to replace a higher watt lighting system. I recommend you to read this article first.

What kind of grass do you have? 陽草/陰草? 紅草/綠草? Although they can grow, are they in the best shape? Far as I know, there are critiques about the W/L. Western and Eastern acquatic hobbyists hold quite different view in this regard. But frankly, I prefer the settings of the winners of ADA's International Aquatic Plants Layout Contest.

i think more light is better than not so much light , but thanks himkelvin and fish fan
