Look hun... like Draig said-- go read the "stickies" on growing & Index in the tutorial section! If you haven't read anything, then you shouldn't be at this stage of the grow yet!
There is a "start to finish" tutorial, and LOTS of them on water, soil, nutes etc..
Everyone grows a bit different, there is no "right " way--
but justt he fact that ya don't know not to use plain potting soil, or when to water, tells me you REALLY do need to read a bit before you go on w/ yer grow-- cuz here-- tho we ALL try to help-- we getthis question (or similar--'tell me how to grow this") every day at least once! SO all these "most often asked questions" were put in one place-- the tutorials!
IF you can't find ALL your answers to ALL your questions there-- come on back to this thread, and ask away!!!
