I think I saw in a video that lumans was the measure of lux, maybe it was not.
I was trying to get a close to it number with the math, but I guess that calculation was way off so 3.75x55=206.25x 10 2062.5 so 2062.5 1 luman per lux is what I thought it was.
Here is the light.

I had to bend the light stand on it because I wanted the lights to be more distant from the top of the aquarium so now the lights are higher, but I don't see anything about the
kelvin or lumans of the light. I have a par meter and it doesn't measure the white light good so that is why I was trying to measure lux. I am not using the blue and purple lights I can turn those lights on and off and the white lights on and off. I am using the white lights.
All the other plants are staying alive in my fish tank now but this one plant is having problems, so I think maybe I got it at a good place and some plants are growing on the leaves, but I don't see alot of growth with the leaves getting bigger.
Here are some pictures of my 55 gallon and the plant that is having problems.

Here is the plant that is not looking good.

The other plants look green but are they supposed to be darker green? The plants are staying alive, but I have not seen a lot of growth. What can I do for that light green plant for the color to be better in pictures that I posted?
I don't know if this makes a difference or not, but my temperature has been staying at 70.2 - 72.1 degrees, should it be at a higher temperature? I have to get a new heater soon that is why it is at this temperature.
