keeping track of ph and other things.

I was wondering if someone could help me out with everything i should keep track of while growing hydroponically. i know i should keep track of ph, ppm. what other things are good to keep trak of and how often should i check these things. and if anyone could give me like a sample chart so its nice and organized and easy to read and keep trak of. thanks.
