Help Required...

[snippetysnip]

Hi all.. a little help would be appreciated as I'm a relative newbie..
Strain is 1st gen Tutenkhamun
Flood & drain tables
2 x 315's above each table, 600 also for last week to try and bush 'em out a bit
Currently in veg 6 weeks
Ph 5.8 (just bumped to 6.0 to increase nitrogen uptake to see if it's this)
EC 1.0
Cal mag added today
Water temp 19 degrees
RH 40%
Air temp 25-27 day, 20 at night (degrees)

The strain is 80% sativa.
1st run in coco the same thing happened to 50% of the ladies
It's happening to 50% again.
They are mixed with cheeses this time which are fine.
I can't remember the name of my part A because I am stoned... please forgive me.... it's the one with the bionic hand held out with a plant growing out of it.
I think I'm cal mag and nitrogen deficient which I'm remedying but not sure if that's what causes the thin wispy leaves??
Any help would be great.. thank you

Death. Your in hydro..... that girl is not worth fixing. Might as well get rid of it and focus on the others.

 

[iKharon]

Looks like manganese deficiency..

@Smerb... they came back in coco.. I know this is different but if they can come back then....
They are only 12 inches tall btw.
In my first post I didn't mean part A was what I'd forgotten.. I meant the "grow" part which consists of A & B..

 

[snippetysnip]

Also there are 20 of them so I'd rather not get rid without trying to recover.

I hope they come back good sir. Your nutes are just A and B? I use a same nutrient type. I've considered that coco is sooooo close to hydro that you might wanna treat it like hydro. I hope your grow gets back on schedule.ill check it out..

A cap huh? Sounds as if your not measuring? What's up?

Yes use a pipett or measuring cup .

Back off any nutes, feed straight water and some bennies, then after a few days add some humic/fulvics. About a week later run half nute strength. Take it from there.....

you definitely have root problems.

have you checked the roots? what substrate are your plants in for the flood and drain? Hydroton? Rock wool? coco?

Hi mate, they are in 3" rock wool cubes which are in clay pebbles in 5 litre pots sitting on spreader mat in the table...

The roots are slightly browner than the healthy white ones btw

 

[hiboy]

All I can say is flush flush flush and start with a low dosage of basic fertilizer and enhancements for whatever stage you're at

 

[snippetysnip]

Ok thanks for all your help guys..
I will take pics of the roots and update later today :mushtache:

 

[guymandude]

probably wouldn't hurt to flush with a H2O2 solution. how often are you flooding?

 

[Tat2420]

Flush...Flush...
Browning roots indicates issues. Are they slimy? I use 2ml hydroguard every water change. It builds up beneficial bacteria in the roots. Roots are lifeblood.
Is there air added to your reservoir?

 

[snippetysnip]

They went on 12/12 two days ago... I didn't want to flip yet but had too..
They are feeding 5 times a day and to be honest look marginally better..

Hi Tat
The roots are slightly slimy but there are white roots emerging next to them... I assume they will be infected over time?
There are two air stones in the reservoir and a circulating pump with a pipe that lets the water fall back into the reservoir also.
I did use White Sharks root bacteria but not continually which was obviously the wrong choice!
Do you think it's worth trying to save these or can the bacteria spread to the others??
Thank you all for your time

 

[Tat2420]

That's a hard choice.
Honestly I would try to quarantine the plants by health into their own reservoirs.
Use a bacteria agent weekly.
I use hydroguard currently. But have heard great things on Mammoth P. I have some and will use it next grow.
I also ph weekly to 6.0 on my strips
Only use reverse osmosis water
Always ph if needed after adding nutes.
I haven't grown hydro in nearly 20 years until the last few weeks

wow. myself... Id start over. and you got some serious typos or your just killing those plants with basic temps also.
