Lst looks fine to me 👍🏻
And about the lights:
All depends on your growing space and the fact that if you don’t grow with added co2 it’s a waist of power(and money)to go over 600w because plants can’t do anything with the extra watt because there’s not enough co2 to process
And a cmh 315 is a full spectrum light and is perfect in a grow space up to 3x3 if you got one with overdrive like my dimlux cmh 315.you can push it to 380w in flower..I do switch bulbs in veg and flower..in veg I use the dimlux 315 4K (full spectrum with extra blue spec) and flower the 315 3k (extra red spec)
Good luck with your grow ✌️
