How soon do I use nutes?

I just put my seedlings into my soil. How long after they have their first set of leaves do I use nutes? I'm using FF ocean forest soil. I know it has a lot of nutes but, How long before I feed?

It depends on what soil you are using, if your soil has nutes in it then they wont need them till about time to start flowing.

2-3 weeks, I mix miracle grow and seaweed compost with a bag of dry perlite+ soil and a bit of sand. This makes for an intense starter soil for the seed :] It also depends how much nutrients is in the soil you bought. If its lacking then wait about 2 weeks and then start adding nuts but don't over do it!
