My Plants

I finally got some nutrients for my plants but I dunno how much to use on em and when to use it
anybody wanna help me out?!
also, when will I start seeing improvements in my plants growth & whatnot?!

I wait til my plant is about a month old. Then start at 1/4 the recommended strength.

How Do You Know When To Add Nutes? Do You Have To Have A Ppm Meter?
