Questions Flushing

hi guys quick question..  I've been checking out the guides 

 

Flushing Before Harvest in Coco

 

 

A good flush in coco will take about 10-14 days. This will depend on the size of the plant. The bigger the plant is, the longer you should flush for.

 

 

Start off with the big flush of 3 times water as you have coco in your pot. This will remove all nutrients from the medium, and allow the plant to start using stored nutrients in the leaves and buds.

 

 

This flush should be pH'd at 5.8-6.2. Allow the coco to sit for 48 hours, and then water the plant with just water, every other day. This will keep the coco saturated, and constantly flush out any salts that have leached from the plant.

 

 

After 6 or 7 days, do one more big flush. There is no need to pH the water this time, as you want to encourage the plant to use whatever is left in its nutrients stores, by locking the nutrients out in the medium.

 

 

The plant will begin to turn yellow, and can be harvested after about 3 days after the second big flush.

 

 

 

so ive done my initial flush of 3 times the volume of the pot, it says use just water after this so is this non ph adjusted water or adjusted until harvest ?? 

 

sorry guys first time so im not sure... 

thanks
