Welcome to APC! What "soil" are you using under the gravel? The last photo in the second post shows the lights off to the side, shining at an angle into the tank. Is that how it is intended? The lights should be directly over the tank, shining directly down into the water. At an angle, most of the light is reflected from the air to water interface, and never gets to the plants.
