When to add nutrients after transplanting

I am using FFOF. They say not to add nutrients for the first three to four weeks of growing because of all the nutrients in the soil.

I plan on transplanting from a 1 liter pot to a 2 gallon pot. My plants have been in the 1 liter pot for a little over two weeks.

After I transplant should I wait 3 to 4 weeks to feed?

Not a dirt experienced person but i would imagine you wouldn't have to add nutrients yet because the soil mix you use should already have the nutrients for it for the first couple weeks or even longer. just see what happens without adding liquid nutrients to see if any shock is going on. dont wanna feed a plant that wont eat as much as it use to and flood it =D

forgot to add. slowly add nutrients, every week add a little more till u reach the point u want.
