Seedling Nutrients

I'm curios about nutrients for my cannabis seedlings I've always started my seeds in red solo cups with fox farm light warrior no nutrients and that's worked fine so far but I was wondering if there is something I could give my babies in the first few weeks to give them a good head start?

Maybe seaweed/kelp?

Seedlings don't need much. should be just fine with water

You can give them the smallest bits of N

If it ain't broke, don't fix it. Just PH adjusted water is fine. I personally wait until week 3-4 to light feed. All strains are different so it's key to read them.

Superthrive in a spray bottle always does the trick without burning...g/l
