HydroFarm Emily's Garden Beginner hydroponic user needs help

Hey all I recently decided that I would like to dabble into some hydroponics and mix it up for a change. So i just bought a simple little system to get started and see what happens from there. Im wondering if anyone has used this system before and can give me some pointers such as, cleaning, nutrients, common problems associated...etc
I am using a 400 watt apolo MH and HPS light. The system came with Microbloom, Microflora and one more that I cant remember. If anyone can help me I would be very appreciative.. I have a ph test kit with PH up and down as well.
