I never schedule feedings like that.... my practice is to follow a routine of water/feed/water/feed... when they're in veg state, that might mean I feed them only once a week but when they're in flower, I might be feeding them three or four times a week since they'll go through the water/feed a lot more often. Since you're in Week 8 or 9, just feed them what is recommended for that age - and if it's three times a week, it's three times a week, if it's only two, then it's only two... Lift your pot up to see if it's heavy or lightweight... the pot will tell you when it needs something more...
Good luck! Looks good!
