Yes, if you have 2,600 w and its 2 ft away on your plant that is sufficient. At in a day your really wanna put your forum underneath the light and feel how intense the light is on the plant. And if the plant is getting yellowing and its is direct to the light that means that the light is basically forcing the plant to work harder. They were going through heavy condition and they were not able to process and grow insufficient and effective as others. The biggest thing is, 2ft higher is more than fine but you can actually go much better. The best thing is to acknowledge the environment. What was the light doing directly underneath? Is it really hot? Is it burning the plant? so, just make an effort to rotate it around. The yellow is because the light is creating more photosynthesis to plant and they were working harder.
