Hey Charkie. How are ya? Glad to have you. Go intro yourself in the Intro section. Depending on what medium you are using. I use Promix which is really low in nutrients so I can start feeds about 14 days at 1/4 strength. You wan to start light and work your way up from there. Autos are more sensitive than photo plants. You can do slightly stronger feeds and run feed water feed or lighter feeds and run feed feed feed every time. Any other questions feel free to ask. Take a look around and read as much as you can in the New Growers Forum. Muddy and Jackal are official helpers, but I help too. Don't bother looking at my grows, they are a great representation of my character, but not of my grow knowledge. I know more than I can do basically.
