Hello I would say your far better harvesting slightly late solely due to a better yield but if its only a matter of a few days it would not make too much difference.
Just keep an eye on calyxes and pistols coupled with trichome colour. You want nice swelled up calyxes and for the trichomes a not to be sparkley basically.
People say that the higher the percentage of amber colour to cloudy will be more of a sedative effect, more cloudy than amber more of a cerebel effect but I never have the patience to leave the plant past the point of a slight percentage of amber.
A lot of people ask me when they should cut theirs down , usually I reply saying when it suits you. Just be aware of the stages of the trichomes, the effects and that the longer you leave it the more yeild you will harvest, this may be a slight difference to a massive difference by letting all of them small buds swell proper. There are optimum stages at which you should cut each individual plant but at the end of the day they're yours and you do what suits you best.
But I would always say better late than early also the later you leave it to a point, in theory will produce more terpenes resulting in better smell and flavour.
I rambled on a bit there but basically early you will have reduced yield, flavour, taste and effect.
Late you will have better yield ,better tasting smelling bud and perhaps more of a sedative effect.
You decide, what suits you best but be aware of the consiquences of harvesting early.
