It depends on your soil actually.

if you are just giving water during its life-cycle,yes it must be ph you dont want to change your media ph percentage

if you are flushing because you have a buildup,then the first 2 buckets can be any water,the last bucket must be at your desired ph
that way you can bring the plants back to square one.

IF you are doing a last week before harvest flush,then it can be any water.Plants will drink water at any ph
but they do require certain ranges to pick up the nutrients.

^ good comments imo. If you're using good soil with a buffer like lime you should be ok. If you have hard water, go buy water.
ONLY adjust PH if you're monitoring your PPM levels. Over the counter PH adjusters can quickly jack you're ppm's up. Especially if your water is already high in parts per million. I worried about ph so much in the past and had a lot of problems. Bought a ppm meter and stopped adjusting PH. All is well :peace:

From my experience you don't need to PH your water outdoor, but then Italian soil is totally different than yours. If your water goes over 7,5, and your soil doesn't have a healthy biota and is prone to water logging, then some adjusting might be necessary.
