the worried thing is normal.. especially for your first few grow.. : )
like a first time parent I gues.. you don't want your first kid to smoke weed. and then by your third kid your like "whatever"

hahaha

your watering regiment really depends on your soil mixture and temp.... it is always recommended to flood and let dry... flood and let dry... but some people just water their plants a little everyday.. I think that ,ethod is crazy and is what leads to root bound plants and the need to transplant... if thepot has equal water and oxygen everywhere, then healthy roots can fill the entire pot...

did you mix perlite in your soil? always a good idea.. helps prevent over watering...

your plants look good.. can you post more pics...
