Led with a hps in the same room

I am about to flip to flower I have a mars hydro ts3000 and I am going to add a 600 watt hps globe my thinking is more grams per watt and achieve 1lb plants I wondering if smarter people than I could tell me some of the problems I’m going to encounter!my environment is pretty dialed in with a low of around 23 and a top of 28 degrees Celsius this is my first grow I have really loved the advice I have received

Plants look good.
What size is the area you are using?
TS 3000 covers ~ 4ft x 4ft
In the middle pic it looks pretty tight to be able to fit a 600 watt HPS in there too.
That would probably be too much light

Looks like a 2x4?

I’d just stick with the TS 3000 in that roughly 2x4 looking space. Such a thing as to much light. If it’s bigger than 2x4 and a bit cold maybe swap out for the 600 just to add some heat but I really think you have enough light
