Is my ventilation set up correctly?

Hi guys, I have a cabinet that's 72" x 36" x 18" or 27 Cubic Feet

I have a 75 CFM Exhaust fan blowing into a Carbon Filter and 2x 25CFM Rocketfish case fans blowing into the cab.

My minimum CFM requirement should be 27cft / 3min = 9 CFM

I also have the following factors that need to boost my CFM:

2x 90W air-cooled LED UFOs (add +5% x2)
3x 16W non-cooled LED Panels (add +10% x3)
CO2 Enrichment (add +5%)
Carbon Filter capturing exhaust air (add +20%)

Total minimum CFM = 9 * (5%+5%+10%+10%+10%+5%+20%) = ~15 CFM

I'm guessing my current fan set up is more than enough for proper venting unless I'm completely incorrect in my calculation as this is my first grow ever.

Picture is attached! I'm 1 day into flowering after a 5 week veg.

Thanks in advance

I think as long as your air temps are good, you will be fine.

my temps range between 22C to 28C with 39% humidity, is that ok? I'm in that trial and error stage of my grow
