I also agree! Get a subscription to high times magazine they cover a mojority of commony asked questions along with pros and cons. I also use soil and red cups along with rooting gel never had a problem and good for mass production!!! I use a pete based soil so I dont have to fuck with soil...
during flowering be prepared for your leaves to yellow and fall off... unless your bloom nutes have small amounts of nitrogen in them your leaves will yellow... I have personally cut off fan leaves and stems during 1st 2nd 3rd weeks of flowering and have had no problems with stunting or end...
