Hey bro I am finally tuning in to your show. First thing, try to get a moisture meter from a garden store or Wally Mart, they are only a few bucks and they even have some that are both PH and moisture meters in one for about $10.00 and they are a nice tool to have around which can help you get used to your babies feeding habits.
Also, once you introduce any dark periods you want to have all light leeks taken care of or else plants can go hermy or have other problems that are stress related, especially in flower. Like GK said if veging for more than 2 weeks you will want to eventually put into 3 gal or more and that being the case make sure you map out a plan in order to fit all of them in your room under the lights with 3 gal pots which can take up quite a bit of room. I use square trash cans that I picked up from Wall Mart for under 2 bucks and they work fine, you just have to drill about 3 dozen holes in the bottom for good drainage.
Well, I wish the best for you and welcome to the world of growing..
