If you have a quality soil that is high in fertilizer you should be fine for about a month . If not just keep an eye for b at deficiencies. You may need to start feeding around the 2 week mark but keep it very light. I typically go 1,1,1, for my first feed then i work up to half strength of what is recommended. When it’s time to flower i go up to 3/4 strength but no higher. During veg i feed every 3rd watering. So if your anything similar youre feed day should have 200-300 ppm. (At your current stage) check a ppm chart for other growth stages.
