When should I start flushing for 7 wk flowering

[my9goesbang]

I have Purple Majik 7 wk flowering time. I'm currently on day 35 (5th week) should I feed her this week or start flushing? I'm using fox farm trio.

I've been following this schedule but I'm confused because this plant says 7 wk flowering time
