Unsure what nutrients you'll be using,but introduce them around the 2nd or 3rd week and to do at about half the manufacturer's suggested dosage. Also invest in a PH kit, soil grows do best in the 6.0-6.5 range, hydroponics and other soilless grows 5.5-6.0. If you're going to grow on a 12/12 light ing schedule from seed....it's a bit of a waste as the first 3wks. will be vegetative growth regardless of the duration of light received. A 1gal. pot should suffice for it's lifespan of going 12/12 lighting.
