If you just trimmed today, I’d wait 3-4 days then flip. Just my $0.02 of course. Your tent looks like it’s getting filled up, and when you flip you’re gonna have 1.5-2.5 weeks of more growth (and faster), so both height and width will become more of a concern.
If your tent has negative pressure (most do, where the sides pull into the tent), you’ll develop flattened buds - which isn’t the end of the world, but one side will always be rubbing against the wall so you’ll look some quality and appearance.
Height - you don’t want your plant to grow higher than the light, otherwise those buds won’t develop as good or as fast.
Other than that, your plant looks really healthy!!
