There are several ways you can develop the anthocyanin in your grow - one is to reduce the nighttime temps during flower (into the 40s if possible) but it sounds like you're past this stage and it may not be economically feasible for a lot of growers. Another way to bring out the purple is to reduce your light cycle during the entire flower period down to 9hrs on, 15hrs off.
A cold water flush with water temps of 40 or so will also help to bring out the purple and some growers will do that for an extended flush of 7 to 14 days but a normal flushing cycle will also work... Basically, in order to bring out the purple, you want to gently stress your plants and these methods will do that....
Good luck!

lower temps at night... this will have a net negative effect but would cause more color to come out.. still limited by whtever the genetics are... but will get autumn colors of some sort. mid 60F is all you need to induce it, though probably better results in the low-60s F.
it won't take much.. bet within 2-3 nights it'll show color.

Ok my take on this after growing countless plants is that anthocyanin development is 80-90% genetics.. so to me, trying a bunch of crazy shit to pull out some color, is often a waste of time.
But the most proven is night time and daytime temps dropping significantly

I just flipped her two days ago and she started growing a bit faster. And looks quite bushy down there.
Should I do it now before she started growing buds? Or should I wait a bit? Or no need to do that at all?
