I just made up my rez at 350ppm tap&VB only, It did require a good amount of ph down to put me at 6. I flooded this time, I'm wondering if I should of just flushed from the top until I get my levels down? After I flooded, it was the same ppm as what I started with. Think my next watering I will just run through the top and then I can check out the run off.
I think the purpose of flushing is to drain to waste. If you had any salt built up in your media, it would have gone back into your reservoir. You say that the PPM coming out is the same as going in, so perhaps there was no build up. You never know what exactly that 350ppm is made up of now. It could be deficient in one mineral and excess of another.
It may not be necessary, but if it were me, I would do the following:
-mix fresh reservoir of 350ppm tap/v+b
-toss old res because now it has who knows what from the ebb/flow
-flush from top and drain to waste until you see 350ppm
-continue ebb/flow with remains of res
This will put you back at zero completely without worrying about what was in the media before.
