Best light mix for autoflower

I am growing a autoflower in a 3 gallon coco hempy bucket. She is just a seedling. I have her in a 2x2x5 tent. I have a 150w hps. I have a mars hydro 300w led. I have a all red led panel. I was wanting your opinion on what light mix I should be using with the 3 lights I have. Should I veg with the mars and flower with the hps? Should I just use the mars or hps alone from the start?

I use a 150 watt hps for my rooted clones and seedlings I have anywhere from 1-20 plants under it (might not be ideal to have that many obviously ) but it works for me . So the answer to your question is the 150 watt hps will supply lots for one autoflower
