I have some questions regarding to the LED light mover

A customer has a question and I hope we can get some opinions on it, thanks

“My plants is on vegetative stage now. The layout of the plant is 8 x 8. I would like to ask you the light mover switch stop to switch stop with how many seconds delay is the best for this stage? I am using one Black dog phytoMax -2 1000 led light on the mover now, but my plant is growing so slow. Also, when the plants turn to flowering stage, do I need to make changes for the light mover delay time? I look forward to hearing from you.”

Delay time? Or they legitimately delay times or veg and bloom switches
