up to you.. could let it go longer and ripen. the stuff underneath continues to ripen, so some happy medium is probably 'correct'. Could also harvest and snip the unripe stuff right off for extracts/whatnot.
plant is still healthy, so i wouldn't let that stop you.. easily roll the nutes back up. if oyu are 5-6 days into flush, maybe a little less concentration of nutes but same balance.
This assumes the plant was the ripeness you wanted -> used a scope to see trichomes and/or familiarity with the plant in question. Look her over.. balance out how much more you'd get vs time invested and .. six in one, half dozen in the other save personal preferences.
