We were all beginners once. So the people who are jerks just let them be. Brewing is a brotherhood of real men. The ones that are jerks, screw em! Like I said we were all in ur shoes once! Here's what I think is best, get books on it and yes, read read read. Also, all grain is and can be VERY advanced. U will see this as u read... Also the way I see brewing, there's three levels, all extract, extract with specialty grains (parshal mash). And all grain. I would work your way up. If u go strait to all grain ur gunna see very expensive gear costs and get overwhelmed. If u feel u get extract, then Move to partial. It's using some grains with still having extract. YouTube helps a ton for visual as well. The books make nice reference material after u read them. Don't worry about making ur own recipes and worrying about how much of what. Use kits from ur local Brew store or the stores online then All u have to worry about is water temps and when to add hops! This is a great way until u feel u can start making ur own beer the directions are fool proof . Also, u need a bigger brew pot 2 gallons just won't do it. Ur idea of just adding water works but not 3 gals of water to 2 gallons of wort. I see that messing with ur PH among ofher things. Get a brew pot that way u can use it when u start to all grain. Something 5 gallons. Then u can boil 4 gals, and freezeq 1 gallons worth, and then use that frozen gallon to help Cool ur wort fast it works like magic!
