low ph in root zone

[Treetrunk]

What EC are you running?

Ec 1.3-1.5

Not sure what nutrients you use but that sounds pretty low to me.
In 4th week of flower I'd be at 2.0 to 2.2 EC. I use Canna or Mills nutrients.
You will get fluctuations especially just after flip and when adding PK.
Can you post any pictures?

What’s your run off ph reading?? have you tried rising ph to 6.5 to see if that makes a difference as of the compensation, I mean like if you up it to 6.0-6.2 and goes go 5.5-5.6 would 6.5 change it to like 5.8-5.9?

I can't measure the run off, as it's wilma system, recirculating, that's the reason why i asking, because the system use same nutrients after run off.

Yes you can tho lol place a saucer under the pot before it goes back into the reservoir that you can check your run off PH then just poor it back in to the res once you checked, this what I have to do when as I’m on a drip table. otherwise it’s just going down the drain before I’ve had chance to check.

If i watering simply i didn't take so much attention to that, but now happens what time to time watering is whit low ph, as should be in 12/12 bit bigger then in veg

Are you changing the water and feed weekly or just topping it up?

Ph swings are normal, they can play to your advantage. The drop everyday is a pain in the bum, but at least you know it happens and the plants are fine, so I;d just roll with it.

Changing weekly, even fresh feed after day i should top up with ph up

My advice is to raise the EC to 2.0 and run that till week 7 or 8.
What strains are you growing?

Jimmy hit the nail on the head, personally i like to mine to rise but either way does not matter as long as you keep it in the zone.
