How long should we flush??

Quick question..

how long do you typically flush a plant before harvesting?

1-2 weeks, depending on health.

so flush for less time if she's healthy or sick?

If you use the 'Emergency Flush' method then it only takes 3 days so you can still give your plants nutes in the last few weeks to help increase yield.

This is how the Emergency flush is done:

I use this method all the time now and it works great.
