No, harvest now, unfortunately you might be a bit late already, so don't wait any longer.
In future, harvest while there are still a few white pistils (2-3%) left for an energetic high, this is when THC is at its highest and CBD levels (which cause the sleepy effect) are still relatively low.
Actuallly, I can see a few white pistils still, so you are right at the point for harvest if you want energetic, but a bit earlier in future would be my advice.
Anyway, chop away!
