Plant Food

Well i went and got some plant food, only when I got there I forgot which 3 #'s to get. The one I got is All Purpose plant food, 20-8-16. My plants are 14 days old. Can I use this? And How much?

It would be ok for Veggin. Start with 1/4 strength per the bottle's instructions and slowly increase as long as the plant is not showing signs of nute burn. It might be too early to give em nutes yet. Maybe wait a few days, just MHO.
