Well your EC should drop daily,means plants are eating.This makes the ph go up.
Yes flush the shit out of them,do it drain to waste.Hand pour water and pump it out to waste.
I run rdwc i fill flush 3 times in 24 hrs until my EC is close to tap.

Yesterday i poured tap water with florakleen and hydrogen peroxide into the reservoir and left it doing its own timed cycle, now i took it out and its 0.65ec

Not enough of a flush. If you have a hose with a fine mist sprayer wash the roots and flood the pots. A few cycles isn’t gonna do shit.

Is a weekly flush of sort necessary? Im asking because the idea of doing it like this (weekly 24h florakleen flush) was introduced to me by local growers. If it is, could you explain how exactly should it be done?

Oh, i forgot. It was sevenish. So dropped a little from our regular tap water ph, which is around 8.

So ph doesn’t drop when it’s straight water but it does when you add bloom nutes

So to say. Although i imagine it didnt have the time needed to do that deadly drop, it usually takes 24-36 hours to drop to red. I took the water out and poured fresh water in, without any additives. Lets see how this turns out.

So now try .5 EC and let that ride a day or two and see if ph crashes.

You should have waited then.

Is it okay to flush for a day and then do that?

myke · Jan 21, 2021

Yea you can flush for 48 hours. Just don’t go full strength when you do add back nutes. Do it gradually.

Man, going down to red is scary. I would definitely chuck those nutes and try something else. They actually make nutes called PH Perfect. I never tried it because I hear it's expensive. GH Floranova is very ph stable. Many others are too. Why mess with finicky nutes?

If its a fresh setup it will take a week or so for the clay balls to buffer up. Ideally when your clay is new before planting you should run them for a week with ph adjusted water. I have the same problem every time I restart.

This could be worth a shot

Now i have been without any nutes for a few days, just flushing it with florakleen and no other additives. They must have a shitload of nutes stored somewhere, the plain tapwater ec is 0.16 when i pour it in the res, and it rises to 0.65-0.50 in 24 hours. Should i keep flushing it?

its your crashing ph that were trying to figure out,This is recirculating right?Yeah the clay pebbles have some build up,perhaps they get too dry between feeds?
So whats the ph doing after 24 hrs of just water?
