nute def.? or what? please help!

Hello guys!
I have a problem with somekind of deff. But im to noob on this so need some expert help!
I have 8 plants in 9.5L pots with LightMIX soil. Im using Gh flora 3 part series nute i have 1x 400w hps and 2x 300w led. Using tap water coming at 6.3ph and 175PPm.
This is my 1st soil grow, i have no trouble with my previous RDWC setup, but now on my 1st try on autos and soil i got this...
1 week ago i just sprinkle on top of soil a bit of Cal/Mag granulate and i think my Royal haze love it the Northen light have only drop leaves but nice growing... the big problem is on White widow leaves... Im watering all this plants like +/- 1L per plant x 2day... 3x plain water than evry 7 days i put nutes at 2/3 strenght of GH watering table.
Soil wasnt overwaterd for shure! Only mistake i do for shure and i know it was a PH. I wrong measured ph of water and i added to much PH- so i think i made soil around 5.8PH. After this i used cal/mag granulate solution and rised ph to 6.3.
Rh in my grow room was 50%-70%, but last week i put the HPS 400w on and now dropped on aprox 40%rh and Temp is around 23oC constantly.
Air circulation+flotuation is on 24/7, Lights are 4/20...
Please let me know if i can do somethink or is better to leave like this...

DAY:48
View attachment 2962296Royal Haze Auto2x Nice dark green but little (red/copper) pionts. <--- i think i soved this with cal/mag... Btw* this strain love high PPM
View attachment 2962302View attachment 2962303White Widow Auto2x <---- no comment?!??! HELP
View attachment 2962307View attachment 2962308Northen Light Auto4x <--- its healthly but sad... :/

Oh yea tottaly forgot i have done some LST on this plants... even a bit supercroping <----- by mistake

Guys help plesae....
I think my solution is to rise PH from 6.0 to 6.8 cos atm im cal mag locked it seems...
Im noob so i need advice if im on right way ...
And any advice how to rise ph in soil?? I have in mind to use a bit of PH + and do last flush with 8.0ph tap water
I flushed with 20l tap water each plant (9.5L buckets) i use Flora kleen from GHE now i will wait 24h than i will put nutes again...

couldn't see the attachments. need need to use the insert image icon 3rd from the right side above you compose window

Cal/mag is not locked at 6 pH except in soil and then not completely So, you are floundering and trying to do to much, correcting by banging the stops, etc. I have been there.

So, you jumped to conclusions, guessed at a fix, and then want us to valid your idea. You are kill plants with tap water sounds like.

Maybe this will help.


It is diferent in types of media.

So, you need to ease up your pH slightly, from 6 to 6.7. But, don't use tap water. That has ungood stuff for plants.

Thnx for reply.
I know my mistake and i know im cal/mag locked but need solution...
When i flush with water ph7.1 at end will drop water ph 6.4 so soil is to acidic. I know when it happen, my 3rd nute round i wrongprepared solution instead for soil use i do a stoner mistake and mixed hydroponic rdy solution at ph. 5.6 and nute strenght to to high... I leave like this for too many time 4 weeks aprox, and some of my plants are reacting bad...
So i need to push ph up... I bought a Hesi PH up (50% Caliumhydroxid) 1 drop of this for 10l water it makes from 7.1 to 8.5 ph i flushed atleast with 20l a 9.5l pot than i measured the ph lvl of dropping water and it become 6.6 but still to low. Cal /mag wont help my plants till i have acidic soil so i sprayed today with cal/mag solution, hope will help...but still need up a bit my ph...
Seems this ph + wont help alot ... im scarred to flush with 8.5ph or more or i maby must try??
ok ill try put some pictures but "inser image" button is broken i can only put 1 by 1 ...
go se pictures on other my post if not working again...

Hmm... i cant use any other water atm... Tap water where im from is at 130PPM and at 6.6Ph, we have rly cool tap water here.
Do u rly think is water my problem...? i do not have any issue in rdwc where water is more important and im using allways same tap water.
When i need to water the plants i just prepare 24h before in closed tank so the clorine will go. I cant improove this atm...
but i thim im just fine on that... Problem is my pot head cos i wrong prepared nute solution :/ instead of doing 1/2 strenght i mixed 100% strenght but for hydro and that is 200% more than auto need... so its tottaly my mistake just dont know how to repair this stupid mistake ...
The royal haze strain need high lvl of ppm so they are nice and growinig crazy but WW and northen light are not taking this good... Will see

Wtf Why i cant post picture in normal way?!?!
I can use only basic uploader and when i upload pictures it will be only link...
Never before...
Any idea??

I thought you said the tap water was 8. And how can a closed container drop the chlorine? OK. A mistake. Do nothing, feed only cal mag tap water until it is better.

Your tap water is fine but leave it in an open tank for 48hrs, not closed, so the chlorine can escape.
You already know what your problem is so whatever way you do it you need to get your ph up above 6.5, if that means another good flush then do it with a weak nute solution, this imo is better than just plain water.

Yea i will try another flush with 1/3 strenght for soil solution... let see...
I noticed all ppl have some issue on posting images this days ...

Thnx guys!
Ermm.. yea opened container ... i dont want lights on water but yea i will leave open

Sorry my bad english

All you really have to do if your water has chlorine is pour it back and forth between a few containers a couple of times to off gas the chlorine. Or add just a little bit of any type of organic material. It doesn't take much at all. And quite frankly there is usually so little of it in the water source that it's another pot forum myth it will affect your grow. I have never seen a difference between letting the tap sit for 24+ hours or using it straight out of my faucet. I will say I am quite blessed with my source of tap, some of the best in the country....

Do u think is better to use with PH+ up to 8.5ph maby??
i have GH flora Micro (hard water) <--- i read around this will lower PH for 0,3-0,5 in 24h

If your tap water is 130ppm then it is soft water, you should use soft water nutes.
Hard water nutes have less calcium and magnesium in them.
If you only need to raise it a couple of points then maybe use 7.5 ph to flush it.

calcium lockout due to ph problem? https://www.icmag.com/ic/showthread.php?t=11688l
like this?
or like this?
or this?


first is calcium deficiency, due to not enough in the soil
second is maganese deficiency, same problem
third is potassium lockout due to pH problems

Tottaly agree! If tap water come lower than 150ppm is still soft water with not alot of clorine...(where i have lived before the water was 300++ppm) We are lucky to with water source... specally for germination is the best i think... is a bit antiseptic just the right amount. I have 100% germination in my tap water and dont have any kind of issue till now... But even now is not water but me :/
I have to flush 8 x 9,5L so this is aprox 150L of flushing water :O and i need to do it quick so i will follow your advice... will see Thnx!

Nizza... I think i have all of this looks like mine... Just different strains different reaction... But yea basiclly i got PH problem i have low ph so my soil is acidic... Cant say how much but if i flush with 7.0Ph water it will drop 6.5Ph... So in my opinion soil is less than 6.5 i worried is more than <6.0... Cant say for shure.. ATM i will try Light nute, Ph 8.5 flushing.... Im waiting dark period atm 2h more of dark ... so i need find best solution in 2h from now hahaha

Can i Spray CAL/MAg on plants??? Because is alrdy locked cos my ph... I wanna help my plants a bit till i will solve ph. They rly need cal/mag... Wondering if spray will help...?

First how did you test your mediums pH? My guess is by checking runoff pH which means dick about the mediums actual pH. Second you will not be able to drastically change the mediums pH by simply pouring pHed water through it. Sounds like you have been sucked into the pH game growing in soil. And now you are chasing your tail.

Yes you can foliar spray, its only locked out from the roots so it will be absorbed by the leaves.
