Critique my setup/first time grow

Hello everyone! I am picking up where my friend left off and he gave me some hand me downs from his system.

I am using a 4 foot tall cabinet, 16 inches wide and 13 inches deep w/ Mylar sheets all on the inside.
180 watt LED.
5 Gallon DWC hydro tote with 8 x 2 inch hydro pots.
3W 7.8LPM air pump dual outlet with 40mm air stones.
75GPH Water pump for drain
140mm 60.9 CFM fans for intake and outake.
Clay pellets and Rockwool as grow medium.
CO2 pad on inside of door.

Nutrients on hand:
Hydroguard
Calmag+
Fox Farms Grow Big, Big Bloom and Tiger Bloom.

I am growing Northern Lights auto-flowers. I have searched the interwebs and found a multitude of information. Most of it conflicting or old. I want to know what the recent word around the block is about this kind of setup and what I should change. Any input or advice appreciated! Thank you.

No advice is too basic, if you feel like its important please tell me!
