When to start nutrition

Feb 25 my seed hit the soil about 5-6 days later there up and running I’m on week 2 almost week 3 which week should I start watering with nutrients? Thanks in advance

When the baby leaves start to fade you can start to feed.
When that is depends on what medium your growing in. Soil will carry them through veg mostly

You can start right now. No big deal. Just make sure it's not full strength or anything

I'm using nutes right now and my cotyledons are still green. I'm keeping PPM of nutes to below 250 PPM until I have a few more set of leaves before upping their intake. I am however growing in a coco medium.
