Well as long as the PPm change is with in range then you did it right. They say it only takes 2 days but I find 4 or 5 sometime is required. I prefer to use the test method my self and it sounds like that is what you ended up doing after all.

Great job :thumbsup:
Zandor Reviewed by Zandor on . Fast Flush Before Harvest - Questions I'm using GH nutrients on one plant (a tree). Unfortunately, I started flushing too late. I flushed with FloraKleen Monday & Tuesday then plain water Wednesday and changed the water again today (Friday). Today is day 5 with no nutes. 3 days with plain water. Unfortunately, I feel the need to harvest right now. Is 2 days of FloraKleen followed by 3 days of water enough to get rid of the nutes in the plant? This plant has been growing for almost 5 months and the last thing I want Rating: 5
