put dimmer on 60% . Maybe 50%. you can play with distance . It would be nice if you had a light meter so you could see what is being given to the plant and also calculate DLI. Also If it were me I would straighten each of those lights up also remember each light is a 2x2 veg and 1x1 flower so watch how close they are and how far apart they are so there are no cold or hot spots I use my light meter to configure the light placement. Go into my profile and look at the pictures you can see the 4 lights placed in a 4x4. the lights on the right are spaced 12" apart from each other. I was growing two plants one side veg and the flowering side I was a giving her some serious light. I also did not daisy chain them I used the dimmers to control each one
