Week 8 of flower is it time to flush?

My second grow first that has made it this far the plant got to tall should've flowered sooner because the thing was touching the lights on the ceiling just wondering if I should start flushing or if the buds have more time?

If you really want to flush wait another 2 weeks then flush for a week. However I personally would skip the flush and just harvest it in 3ish weeks and dry it and cure it slowly.
