Ec keep rising in Dwc

Hey troops, hope you're all staying safe n keeping well.

I have a lemon cake that's 1week in flower and she's not feeding , she hasn't dropped the ec since she sprouted.

Rez temp 20-22c
Humidity 40-50%
Tent temps day max 81f
Night 66-70f

Week 2 of Veg she went super limey in color and ppm's kept rising, pH sometimes stayed stable but other days it would rise or fall a little bit whilst water level went down slightly.

She was on less than quarter strength Advanced Nutrients Connoisseur , and because of what ive read over the years I thought it was overfeeding so I subsequently lowered EC everytime I saw the rise in ec.

A few days later she looked bad and tbh she was basically on tap water at this point (ec0.5)

So on the advice of another I upped the strength from 0.6 to 1.2 and within hours she started putting colour back in her leaves.
Next day the Ec had risen again so I topped off with tap to just below the previous day and the next day the Ec rose again. pH would rise by 0.4 or sometimes lower by 0.2 whilst water level dropped.

Roots are fine , no smells , tiny bit staining because of the humic and fulvic acid and Nirvana. I use tarantula mychorziae too and Rhino Skin.

In the last week the plant started to go limey again so every other day I upped the nutes to 2.0 and she got slightly greener yet again whilst EC went up.

2 days ago I upped the nutes to 2.6ec and the next day it had risen again by 0.2ec and pH jumped from 6.1 to 6.4

I'm not sure if it's the right thing to do but today instead of increasing the EC I emptied Res and filled with ph'd tap water.

Will leave for 24hrs and check tomorrow morning

What should I do in the morning?
Will I see the plant leaching nutes back into the Res yes?
I know to dump that out but where do you all think I should start with EC seeing as it's not a small plant?

Pictures provided will show how light she is , after the first increase she showed a small cal Def which is fixed but after that I saw she has some darker blue green leaf edges and the tips showed yellowing.

Sorry for the book but if I've left anything out please let me know and I will post the info.

Thanks n stay safe man.

Is my plant showing any signs of overfeeding?
What do the bluegreen edges signify?

Does anyone see deficiencies here?

So your tap water is ~250 ppm?

what light is it under-how far away??also empty res and just put base nutrients in without all the extras to start with,and aim for 0.8-1 ec to start!! ph 5.6-5.8 then let it drift up!!

Yeah it's bad , highest I've seen it was 0.6ec

Hi bud, 600w hps and it's about 26to30 inches away from canopy.

I emptied Res earlier and it's been sittin in ph'd water for a few hours now , the pH went down 0.2 , water reduced by a litre or 2 but EC stayed same so far 0.48

Would you suggest doing it now or just wait till morning because my light goes off in an hour.

Is this what you see happening when overfeeding?
The overall lime colour I mean.

up your ec to 0.8-1.0.start from there until you find the plants sweet spot,then try adding extras!!

do yourself a favor and buy a RO unit or RO water. your tap water is too high EC IMO.

After a 28hr flush with just ph'd tap water @0.46 EC the pH went from 5.8 to 4.2 overnight and EC rose slightly to 0.49 while water level dropped.

The EC rising was probably it starting to leach nutes back into the rez.

I made up a new batch of nutes last night in preparation for today and it's at an EC of 1.36 which makes it roughly 0.9ec because tap water is 0.4-0.5ec.
pH was set to 5.6 so will see in the morning how she gets on with that and will take it from there.

Will post results tomorrow..

Thanks

see my post above. it will be very hard to succeed in hydro with your water. my EC in veg is 0.46. lol.

Yeah I agree bro but for now I'm stuck with tap water until I can get hold of an Ro system. I might actually invest in one next run n see how that goes.

Better all round I suppose and even for flushing it would make things a lot cleaner.

i lugged 4 of those 5 gal jugs from walmart to the casa once a week. i finally slowly started mixing RO with my well water and now i'm on only well. but my EC is 0.2. and i know exactly what is in it thanks to a water analysis i get done.

In Scotland (UK) where I'm originally from the tap water comes out soft at 0.2 but I'm in England staying with family and the waters hard as fuck lol and 0.6 is the highest I've seen it.
Kinda disgusting if you ask me and not really what you wanna give a plant but until I get the ro system I just gotta put up with it.

It's manageable but not desirable lol.

I set Rez yesterday to 5.6ph , 1.36ec

Today's readings are 6.14ph and EC dropped a little bit to 1.34-1.35

pH rose, EC went down and water level dropped about 3litres.
Should the ph have risen that sharply?
Is that normal?

What would you suggest I do now guys, should I leave it as is for a few days or increase nutes a tiny bit.

I'm using x700 scale so I was roughly sittin at 950ppm and I'd say it's only dropped 20-30ppm overnight.

sounds a bit more stable,from your water source are you filling a tank or tub and letting it sit before taking readings of ph and ec??if not try that,might not make too much difference.But your ec looks more stable.

Yeah bro I fill another bucket and let it sit overnight , when I give it to the plant I also check again after an hour or 2 just to make sure it's where it should be.

Im just glad I'm seeing it go down man , for 4wks all I've seen is daily rises so yeah I'm over the moon with today's results.

I take it I wait now or do I increase strength?
I really don't want to push it and it's only a drop of 20to30ppms so I guess I could wait a day or 2 then increase if she's still dropping.

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.

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 wouldn't try to change the ph when using buffered nutes. Let the buffers do their thing.
