Help needed Dwc roots have stopped growing

[Budman1487]

Hi guys I’ve been growing in rdwc for a few years now with minor issues , this time around i transplanted clones to system a few weeks back hand watered till the roots come through and started growing in the water nicely then all of a sudden the roots have pretty much got to a stand still and the leaves are showing signs of what I believe be nitrogen deficiency I may be wrong though .
the roots don’t look to bad but just not growing , I’ve upped the nitrogen in the feed but still doesn’t seem to be helping. Water temp is 18-20 constantly .
I’ve tried fresh water and nutrients and even added some hydrogen peroxide , the air stones are all working fine also , I’m just a little baffled to what has caused this. I’ve uploaded some pics of the clones and the roots .
any help would be much appreciated.
im thinking of cutting the roots then hand feeding till new ones appear but hesitant to do this as the roots don’t look to bad.

 

[rkymtnman]

sound like root rot. or overfeeding. pics?

 

[Budman1487]

Here’s a few mate

 

[rkymtnman]

looks like a combination of slight root issues and probably overfeeding or pH issues

ec/ppm is?
ph is?
i would use the peroxide constantly or switch to something else
ditch those clear air lines for black ones

 

[Budman1487]

So ec was 0.70 when I put in then I’ve increased to about 0.90 now plus added extra nitrogen as I thought it might have been a deficiency .
I’ve been putting in hydrogen peroxide at 0.7ml- a litre a instructed in the shop .
Ph has been within 5.8-6.3
Ok will change them over does that help then with black ones ?

 

[rkymtnman]

when you were at 0,7ec, was it dropping daily? staying same? going up? i'd go back to 0,7 don't add any more N either.

i've never used peroxide so can't help you much on that

pH is good

clear lines will let a slight bit of light into your res which can lead to problems. better to use black and not worry about it

what is your grow room temps?
i'd turn down your lights and try to baby them and hopefully the new growth starts to look better

 

[Budman1487]

The ec was pretty much staying the same .
The room temp is about 25-27 then humid about 65-70 I’ve got a vpd reader and I’ve been hitting it spot on at 1.0 which is normally all fine for veg.
I will try turning down the lights and have lifted them up a little .
Do you think I should cut the roots and hand water till new ones or keep them ? From my experience they have looked that colour before and haven’t been to much of a problem?

Thanks for the advice her buddy I appreciate it

What % is the peroxide?

 

[Budman1487]

SMFH....GARBO!!!

PLEASE...Just Buy Weed...

WASH YOUR FUCKING GROW ROOM ...Damn!!
Are You In The UK?? If You Are, Ill Spare You Some BrimStone

1. Its Not Your Lights
2. Its Not Your Clear Air lines

I dont know WTF you did but Your Nutrients are Locked out...
YOU Have been grow RDWC for a few Years...?!
Why did You transplant & from WHAT did You transplant??

WHO THE FUCK Is Giving You People CLONES??? ...STRAIGHT Violation!

Do You even Have a Happy Feel Good Story...
Oh yeah, My buddy fucked up his grow...so I helped him out.,,

Wow
I’ve just come on here for some advice mate I’m not an expert what I’ve been doing so far has worked for me . The room will be cleaned it’s just having the time at the moment .
The clones were in coco pots so I washed all the coco of with a hose then put into Pots and hand watered , I’ve done this everytime and no problems , the roots were growing fine then they stopped all of a sudden .

 

[Budman1487]

What % is the peroxide?

It’s oxy plus 12%

 

[smokey0418]

It’s oxy plus 12%

At 35 it’s 2ml/g , so at 12% that’s 6ml/g.
Feeding at 1ec should be fine.
Thanks what I think.
Believe the math is right now.

don't pay attention to that jibberish. most of his pics have major deficiencies

 

[Budman1487]

WOW...

I knew It..
Shit wasnt adding up...
You Know What to Do...Fix It.

1. extend your grow a FEW MORE Weeks...Get You Plants Back In Order...& Keep working
2. Cut The Stalks in Half...Root Them & start Over.

I did the same thing...WENT FULL Soil & Freaked Out cause It was Like Watching Paint Dry
Then transplanted BACK to DWC

I don’t know what to do mate that’s why I’ve come on here for some help.

Yeah was a little harsh im only looking for some help. I will give what you said a try anyways thank you for your help bud

Yeah that dude is all over the map with his ramblings. try what rkymtnman said. Also up your peroxide dose and hopefully they turn around

just take it easy on them. you'd be surprised how much abuse they can take. and this will be good practice on how to save your plants. people are too quick to say cut your stems in half and start over. that's nonsense.

since you said at 0.7 ec it was staying steady, i'd cut that in half to like 0.3

if you keep your pH in range, don't get root rot and don't overfeed, dwc and hydro gets a helluva lot easier.

Thanks mate how much do you think I should increase it by ?

Yeah that seems abit excessive recutting them stalks . The leaves are still slowly growing but after a day or two the new leaves start to crisp up and go yellow .
but no growth on the roots .

Yeah when all is going well it’s such a easy system to use just a puzzle when it goes wrong

I will try lowering the ec and see how that goes

 

[smokey0418]

Thanks mate how much do you think I should increase it by ?

The teachers still ask to show your math.

2ml/g at 35
Or 6ml/g at 12

1g is equal to 3.875litres

6 divided by 3.875 litres is 1.55ml/l

so close to double I would think.

How are you measuring your EC? what pen/readings etc?

They look like they are getting fried.. I was gonna ask also what light/intesity/distance you are using? but it does't look like light burn, but it would be usefull to know aswell.

They look like they are being cooked from too much fert... maybe stop with the additives, just add water to dilute the EC down a little bit, they are only small plants so maybe drop the EC to 0.5 or less? and see if they look better over the next week?

Disclaimer, I'm kind of a noob at DWC, but i'm sure the replies above offer some decent advice.
