These are autos so they don't like/don't need nutes for the first couple of weeks.... I would start additional nutes at about week 3 but only about 1/4 strength to begin with to make sure the nutes will be tolerated.. If they ARE tolerated, you can up the dose to 1/2 strength week 4 and then plan to go to your bloom nutes week 5 (unless she's in bloom week4 which she might be)....
Good luck....
