Got $2k budget for a closet grow

Hey everyone! I'm planning an operation for a 3x3 tent closet grow. I've been researching for months and have most of it figured out except a nute schedule. I'm thinking I'll go half recommended doses with weekly flushes and get a feel for it as I have yet to come across any solid advice for aero.. I'm going with a 300 watt Advanced LED DS light, homemade aeroponics.. At first I wanted 9-12 grow sites, but after careful consideration, I've chosen a small 4 plant set up to see if I can master defoliation for a larger yeild. The first few harvests I will pamper 2 plants and stress the other 2 until I'm confident which strategy yeilds more.I will be able to control temp, PH, EC, humidity and CO2. I'm looking forward to meeting some experienced growers and will be sharing my own experience and knowledge as I learn more about growing marijuana.I'm always open to criticism and/or suggestions so feel free to comment as you see fit.

A) dont waste you time with aero unless you want to go all out meaning high end pump and timer, specialy nozzles and a lot of work.

B) co2 is good a controller or monitor is a nice way to go.

c) have you thought about eeb and flow? you can run more or less plants as you see fit with much less restrictions it is also much more user friendly.

D) i would build an led light personally for what you will spend on thier light you could build a much better one for the same price. me id stay away from leds as my main source of lighting, and use a smaller panel in combonation with HPS.
