I recommend General Hydroponics for beginners. It seems to do a good job and doesn't cost very much. There is also plenty of information available as its seems to be a common brand.
Goodluck
Yah you can use vinegar and baking soda for that though. Whats a tds or ec meter?you also need ph up down, ph meter and a tds or ec meter as far as for the water

General Hydroponics seems to do a good job of balancing the PH on its own. I will have to check out Holland's Secret and report back my findings.
