Quick Q about Nute Schedule

Hey I just realized the flowering nutes I used on my last grow were not for veggies, just for flowers, so I went out today and got myself some Advanced Nutrients Sensi Bloom 2 part, but what I'm wondering is the nute chart on the site, since I'm using soil, in the res size area, do you use the size of your watering container as a guide for how much, or is it the plant container? I'd hate to basically double up the nutes for nothing...

Its for the watering jug.

awesome, thanks!
