Flushing question

it's day 25 of flowering and i literally can't feed one of my plants fast enough (seriously it's a 10" continuous bud already) despite getting a 1500 ppm dose of Grow Big/Tiger Bloom/Big Bloom. Leaves changing color all over the place and It's been about a month since I flushed, so i figured it was time.

My question is, do I have to follow up the flush with a weak dose of nutes since I just flushed all my ferts out or do I just wait for the next feeding and feed the scheduled amount, 1150-1330 ppm?
