Will my set up work? Is it missing something major?

I agree with both Hashy and Grannie. Grab a fan or two so air can keep moving and watch how much you feed them. Autoflowers don't seem to like too much food, so you may even want to go 1/4 - 1/2 strength, instead of full power.

Your set up looks perfect - and that light is exceptional! Pots are fine and an absolute "YES" to nutrients. Don't give the nutes to them until they're about a week or two old and then do so slowly - 1/4-1/2 strength... with autos, less is more and I've never grown one (autos are all I grow) that can tolerate full strength nutes. Biggest tip: always pH balance whatever you give them (water/nutes) - it should be between 6.0 and 6.5 - you'll avoid a whole lot of problems if you do just that one thing. Good luck and enjoy your journey!
