Ec keep rising in Dwc

29menace said:

The sharp rise in pH , is that normal?

I take it you would reset the pH back to 5.6 when you top up the tank and let it rise again.
Would there be a point you wouldn't go past with pH, and do you think it's just going to keep rising as the ppm's drop?

If the answers yes then should I let pH get to say 6.2 then reset it and top up the tank whilst doing so.?

Soz for all the questions bro I just wanna get this right as my Gorilla Zkittlez from Barney's Farm was a Hermie and I've only got this one left to play with.

Thanks for stopping by.

Ignore the arrows, its from another site

Thanks guys , glad of the help coz I just lost a Gorilla Zkittlez and the lemon is all I got left.
Will up the strength in morning a little bit and see how she gets on because I don't wanna push it too much right now.

Barney's Farm is horse shit for Hermies , beginning to think they don't even test there genetics anymore and that were the dummies doing the testing for them.

Because it's illegal here and in most countries not many of us have a leg to stand on. I can't complain ,I can't do shit about it but there getting away with scamming everyone.

some of the Nirvana stuff is pretty solid. aurora indica was a really good one i thought.

and i wouldn't increase EC at all. a 20 ppm drop per day is just about perfect.

Yeah bro I grew aurora 2yrs ago , great strain man ,high yield and packs a punch lol.

Thanks again for basically talking me through this man, without your help and knowledge bro she'd have fried by now. What's she's on now is about a half of what I had her on so I'm happy man ,and no doubt she'll thank me too in the end.

lot of people talk shit about nirvana but that one is really good i thought too. i did a bunch of their beans years ago. some were average, some bad and some really good.

and yeah, less is more as far as nutes go. i usually am around 0.8 to 1.2 max EC. since the roots are always in solution, they can eat whenever they want to.

keep your pH in range, your EC dropping slightly always and don't get root rot and dwc isn't too hard. good luck!

waht part of Scotland were you from? i did some work over there many yrs ago and would love to go back. awesome place and great golf. and Lagavulin. lol.

Yeah I know the place ,, I'm from the west coast of Scotland (Inveraray Argyll) tiny little village in the middle of nowhere lol.

I'm living with family in Derby England just now but do plan on going home soon.


I have grown a few of Nirvana's seeds over the years and I think there slightly more stable, well some are compared to all these new seed Banks that we do the testing for lol.

agree keep ec the same untill they tell you they need more or less,and i usually set my ph to 5.6 and let drift to 6.4 then back down again,once you get ec stable should take a couple of days for ph to rise,well it does for me anyway.good luck and stay safe!!

Thanks for popping in buddy, the EC seems to be doing what it should now. Today the EC was 0.1to0.2 lower than yesterday and the pH is now at 6.2 so tomorrow I will top up the Rez and up nutes to 1.4ec lower pH to 5.6 and see how she reacts again.

I appreciate everyone's input on this thread so thanks again bro.

hi sorry to just jump in but im using ph perfect sensi grow and have had to dump a couple grows down to slow growth no growth and ever rising ph water out of tap is 7.8 ec 0.2/.4 ro is not a option at minute my question being you say you ph down your water but AN ph perfect is cheleated and is supposed to buffer set ph to perfect level but i find this not tp be the case it doesnt lower my ph enough anyway basically is it ok to ph down the water after adding ph perfect nutes and haveyou seen any adverse effects from this thanks

I know that they say you don't have to pH but after I add nutes my pH is still over 7.0 so I add it until I get to 5.6 in hydro Dwc.
I haven't noticed any I'll effects from doing this ,, once you bubble the tap water overnight I found it takes slightly less pH down and once it's set it stays pretty much bang on all the time.
They say it should do this all by itself but I haven't found that to be true with UK hard water.

I just ordered an Ro system from Amazon and it should be here Sunday , it's only £41 and does 50gallons per day and fits under the kitchen sink.

With Ro I'm going to test connoisseur and I will let you know because I wanna see if it sorts the pH itself without me adding pH down.

Forgot to mention I've had slightly more fluctuations in ph using sensi than I have with connoisseur but sensi is still very stable imo.

You soil or hydro?

thanks for the reply im hydro been that way since day 1 wilma kit drip system then i went over to rdwc last year had some decent result using ph perfect sensi grow and connoisseeur bloom big bud and overdrive (decent in my opinion) didnt really ph at all but this time round had some issues with growth or lack of it leaves yellowing out from the middle and due to lockdown struggled to get hold of ph down untill now set it to 5.5 yesterday evening(it had floated up to 7.9) x-stream propagator (c-99 seedlings)will be checking it shortly to see where its at as for the ro water would like to go down that route but the other half moans im taking enough space already although the ro wouldnt take that much space and please do let me know about the ph with connoisseur

29menace said:

Because I'm using advanced nutrients pH perfect I'm not sure if I even need to worry about pH.

I will however follow the advice given here and ignore the pH perfect for now and will pH when I see it's needed or if I'm told to raise/lower it.

Anyone here using Advanced Nutrients Connoisseur.

I used it in a drain to waste medium, I had ph issues, I tried it in 2 grows, I gave the stuff away and moved on, works for a lot of guys but didn’t for me. Personally I rather control my ph after the experiences. If I went back to AN (which I won’t) I would prob pick a different line. This was all with 4ppm Ro water. I do use the AN ph down, good stuff, don’t think they make it though.

yeah ive followed 29menace approach and to be fair its working out so thanks where thanks is due ph down to 5.5 yesterday afternoon 1pm ish checked it this morning it had drifted to 5.9 checked as of 5pm uk tonight its still at 5.9 will maybe leave it for tonight and then drop it again tomorrow so that the little ones get the benefit of mild swing in ph instead of the issue of hitting 7.9ph within 3 hours i understand AN is supposed to set the ph but ive started to believe it aint true its just chelated to be available higher or lower down the ph range which has worked for me before but this time round i had issues the c-99 i got going now are doing exceptionally well compared to last couple attempts that failed badly

It's good it didn't rise like before so it should be plain sailing now bro. I let mine swing a little but I find it wants to creep up and sit right about 6.0

It pretty much stays at that all week if I don't drop it back down myself.

That’s great news, hope it stays stable for you.
