You can run plain ph'd water up to two weeks at the end of your grow.....I would start flushing the BB at the normal time (perhaps with plain water and no flushing solution) and just continue to run them both with ph correct water until they finish......again......you can keep the WW on plain water for up to two weeks before harvest so hopefully that will be enough finish time for the WW. I personally dislike the taste AND the way the weed burns when I don't flush it......tastes metallic and very "crispy" and "overdry" (too many salts? )
Weedhound Reviewed by Weedhound on . Different strains same DWC, when to flush? Well because of a recent move and a baby and many many other distractions, my latest grow had been thrown together a little sloppy. I had to start from seed and and ended up with only 2 females out of 10 seeds :(. Anyways, the females that I ended up with were one white widow and one blueberry. It appears as if the blueberry will finish about 5-10 days earlier than the white widow. The problem is that I started these two plants in the same 13 gallon rubbermaid dwc, and didnt even think Rating: 5
