It has nothing to do with the light.
When the leaves are "praying," the plants are doing very well. This phenomenon occurs when the turgor pressure in the leaves is at its optimum. This means the osmotic pressure between the medium and the plant's roots is perfect, allowing the plant to take in just the right amount of water.
Osmotic pressure = how well the plant can absorb water
Turgor pressure = water pressure in the leaves
Your plant is doing well. You're doing something right. :)
