PH 5.7-4.7 in 12 hours. DWC

600 to 511 to 580 is not trending in the right direction

top off with RO until your ppms are at 400, adjust pH, and see what happens.

I didn't think so either.. plain ro or a touch of calmag added...
This is the noob in me asking

if it were me, just RO. see how they do at 400ppm if the ppms drop continuously for about 3 days, mix up a fresh batch of nutes at 400.

I think I've seen that somewhere before tbh..
But the fact ph has been stable for many weeks.. and drifts up slightly as normal if not altered allowing a swing which lve seen is good for plants.
the sudden drop over short periods of time stump me...
I'm not ruling what your saying out at all.. just ph been fine for so long even though it seems EC needs reducing over the last few weeks

I don't know if anyone else has mentioned it. Excuse me if they have, but dropping pH can be a sign of an infection. I'd clean everything up and keep your res temps in the 60s.

Well tbh.. I'm confused as fuck here as to what's going on. I cant check for a few hours yet as lights are off... and writing this I'm 9 pints in.
Rkymtnman you seen yourself I dropped ppm and should have just just flushed.. thinking I solved a problem after I did and now there's a change.
I dropped ec several times before deciding to full flush with pure RO and now this.. lol..
Imma sleep.. then check things cos atm I'm fooked too many captain mrgans

can't ever have too many captain morgans in my opinion.

the only thing i think you should have done differently is come back after the flush with way lighter nutes (like 200 to 300 ppm vs 600) and then work your way up. my max ppm in my entire grow is 600ppm or less just to give a FYI.

and like @curious2garden , myself and a few others have asked, are we as in you 100% positive we don't have any root rot going on?

Ok.. I've been away. And this forums been down obv.
Only managed to top up today.. but the res was that low I decided to replace the full res again.
The ph was stable.. drank about 35L since last top up. Ppm was 610.

New res ppm to 120 with calmag then to 320 with maxi.
Ph'd to 6 and left it at that.
More leaves showing signs of I'm assuming nute burn.. no real sign of improvement or growth..
Checked roots.. and I'm sure from what I can see there's no rot. But the root ball is big.. I can only see the exterior.
Will try and get more pics when lights back on.
Cheers JG

(PS.. definitely too much Morgans was consumed )
