never done hydro but it seems pretty obvious you are gonna hvae to do something to bring it back up because i don't think the plants are gonna like that for long, maybe dilute it with fresh water then test the e.c and add nutes if needed. they looking ok still?

Yeah im with hulk on this one, hydro aint my thing lol

Only nugget i prob can offer is after reading a convo the other day how long are you leaving the water to stand before ph`ing etc? Also once you have ph`ed it, have you ever left it to sit for a few hours then tried ph`ing again?
As some ph solutions can go all out of whack within an hour or so of water being ph`ed n left to sit and a few hydro ppl ive seen talking with larger tanks (over 150L) all reckon they need to ph twice in larger reservoirs, once initially then they have to leave the solution to sit for a while then re-ph it again an hour or 2 later

I only ever pH the 20l jars of feed when I'm filling up the res with them, never usually check the res cos I see no need, plants look good. But since u asked I went and checked, its sitting at 6.1 and that was 3 days ago I fed it with feed at 5.8........so its ris by 0.3....dunno what's up with urs m8, I'd empty it, clean it and fill again and keep an eye on it
