do you ph the flush water?

Should one ph adjust the flush water in a aero/nft system or does it not matter because there is no npk in the water?

i flush with plain water none ph-ed unless i am usin advance final phase then i ph to 5.8 for a few days then flush with plain water none ph-ed ......hope that helps m8

Always pH your water.
If you don't, you can cause a pH fluctuation (which in turn can harm your plants, even in late flowering).

Why should it be any different how much the plant is into flowering?
Nutrients aren't the only substances reacting to pH levels.

Plants watered (or flushed) with tap water / plain water almost always exhibit signs of pH fluctuation due to the grower pH leveling the water up until the plain watering.
A jump from 5.5-6.1 pH in a hydro grow (optimum range) to 7-8 pH (tap water) can very well cause problems.

On another note, not everyone flushes.
Hence the need for constant pH control to not stress the plants.

neva had a problem the way i do things and it sound like u dont have a problem with ur way.... i neva ph my last flush any way this sounds like a neva endin story so i am gona leave u to it my gud friend......take care

I never adjusted my flushes either, but I think i'm going to try it this time, i dont see it hurting anything
