jena, you start off with 1/4 strength and move up per feedings. for nutes I use Fox Farm grow big for veg 6-4-4. for flowering I am using Kool Bloom 0-10-10 and Fox Farm Big Bloom 0.01 - 0.3 - 0.7. when you start mixing your nutes, start with your first feeding at 1/4 then move up in increments. PEACE!
