Second time around

I am having better success this time around. My questions should I start feeding nutrients? And if so, would Dr. Earth granular veg blend be ok to feed it? Soil is Happy Frog. Currently under 18/6 light schedule. Thanks guys and gals!

I wouldn't start just yet....the soil has nutrients in it. When the cotyledons start to yellow, that's when you want to start feeding. But first feed should be no more then 25% and work your way up.

I have never used those products but from what I read the Dr Earth granular says "nutrients are released quickly" and "feeds for several months". I would hold off for a week or two before adding. I use a 0.05-0.0-0.0 potting soil and typically wait 1-2 weeks before adding nutes when watering, the Happy Frog should be able to feed that seedling for longer. As said above wait until the plant looks like it needs it.
