The site format has changed since I have last been to 420mag so I hope this is a valid thread for my question. I have done a fair amount of research regarding my concern and have found little that deals with it directly. For growers with limited space requirements, growing plants under a 12/12 light schedule from seed is a viable option. I myself have completed numerous successful grows (indoor soil) under such conditions. However, with a 12/12 light schedule the plants are forced to flower quickly, making applying nutrients very tricky. Without the obvious vegetative vs flowering stages I am wondering if anybody has a reliable method for using nutrients. For example, the window for using nitrogen is very small as plants will begin to flower in less than 3 weeks from sprouting.
Remembering this is an indoor soil grow, what are your suggestions?
