How long b-4 harvest do u stop nutes?

Well coming close to an end with my Ak-48's which have been a real pleasure...packed on a ton of big, beautiful buds...how long b-4 harvest do u stop nutes and just use water...my nutes are botanicare's pure blend pro bloom, cal-mag, bio-bizz topmax...on my first harvest i forgot to flush and had some harsh bud...how long b-4 harvest do u stop nutes...also should i use to topmax until the very end since it is a flower sweetener/booster? forgot to mention i grow in happy frog potting soil...thanks in advance :thumbsup:

stop using nutes and flush the last ten days of growing as for the sweetner i would stop using it too and just use a plain water regime now:thumbsup:

depends on the grow and if you flush them correctly. swim does for 7 days and smoke is always beautiful. But swim also doesnt over fert like alot of people
