Should i harvest it or wait a bit?

I don't think your plants ready for harvest yet, but if you only have 1 week then you gotta do what your gotta do. If you where to leave it on the plant and get to it later the plant would be so over ripe and amber it would act as a sleeping pill and put your brain on pause. Flushing with out the need to do it will strip the medium of all its nutrients and the plant will start to cannibalize, it does not do anything good for it and flashing is a bit of a myth if its not needed, The only time it is needed is if you are doing it to avoid a catastrophic event like you feed way to much, the PH is very wrong there a best in the medium that needs treatment. Doing it end of grow in the mindset the plant will use up its buildup nutrients in the plant is a lie, its not how it works. they don't store nutrients in buds. So yea, harvest as late as you can, dry it and cure it and hope its ok. The buds look immature right now and prob will be very light and fluffy however they should still get you high. Good Luck!
