Tapering/slowing down your nutrients towards the end of flower will be a lot more forgiving to your harvest rather than overwatering the root system, which can slow down those last few weeks especially if you already got root problems.
Fwiw, some people refer to flushing as tapering down or using water only towards the end and others think its pouring 5x the pot volume one time to get rid of "nutes" stored in flower. They both do different things so when somebody tells you to flush, it doesn't always mean to overwater your roots to death.
In soil with balanced ratios and no excess, pouring 5x the pot volume doesn't make any sense and is bad for your roots and humidity levels which is still important in those last few weeks.
Honestly though, it is your grow and you are free to try both, just pay extra attention on how to dry.
THIS IS THE TRUTH!
Look to your leaves to let you know.
Sick, pale, washed out, falling off on their own when it’s not a light penetration issue.
These are all signs your plant need nutrients.
You cannot flush nutes out of a plant. You can only flush nutrients from your growing medium.
Plants transport nutrients as ions.
Chemical nutrients = ions already available for direct uptake by your plants roots.
Organic nutrients = microherd has to convert organic compounds into ions for uptake by the plants roots.
Ions are ions it’s just how they’re acquired that’s different.
No need to “flush” hydro grown either.
