help save my blueberry northern lights!!

[chongsbuddy]

I have a blueberry nl from dr atomic and it is growing in soil,which i water every third watering.The ph is good and so is the ventilation.The last feeding,i gave it a good shot because i was feeding really light,i dont have an ec meter.Can you tell me what this is and how to fix it?

Looks like old age. From what I can tell the plant looks like she is close to finishing. It could be your fan leaves are no longer productful and they are leaving you naturally. Not too worry, it's a normal course of events.

deffenetly looks like ph swing 2 me......but what do you mean ph is ok, ph of the water/feeding or soils ph...theres a big diffrence... how much is ph at ?? btw is the meter callibrated?

ohw and what does your soil contain..

but wait for more repleys i just stated my

 

[chongsbuddy]

I ph the water every time to between 6-6.5,even the run off ph is perfect,or was,I'll check it again tonight.I thought it might be a magnesium def,but i really dont know!I dont really know what you mean by old age,the plant is only 4.5 weeks into bud!

let your medium,container dry out.

What are you feeding them.....????

 

[chongsbuddy]

I feed them dnf 2 part,at 1/3 strength every 3rd watering.

looks kinda like a calcium deficiency, that or just pH lockout, but you say you have the pH down.... if you can get an EC meter, I highly reccomend it.

 

[chongsbuddy]

Ut could be calcium because i have no dolomite lime in my soil.

 

[ourcee]

a lot of tap water has fairly high calcium in it (unless you have rediculously good tap water where you live). maybe you could pH adjust the tap then water with that...

however my reference to a possible calcium def is because of reading Stitch's sick plant guide probably 20 times over

http://www.icmag.com/ic/showthread.php?t=11688

scroll down about 1/3 of the way till you see the section on calcium and you'll probably agree that your leaves look like those listed under the cal deficiency..

again having a ph/ec/tds meter I feel is invaluable

I have some trainwreck and OG that EASILY eat up my (at least I feel so) high nutes (~1500-1800ppm)

if your feeding lightly every third watering, its probably just a nutrient deficiency and those are usually pretty easy to fix.


good luck

my god i think youve got it man!thanks alot!!!

Greetings chongsbuddy

Dutch Nutrient Formula possesses an unstable pH in solution. The concept is to allow the uptake of different nutrients at different intervals for rapidly growing plants in a hydroponics system (this is the translation of "maximizes nutrient uptake").

When using (in hydroponics), it is recommended that the solution be changed weekly for optimal results; failure to do so often result in nutrient imbalances.

Can you tell me what this is and how to fix it?...chongsbuddy

It is a nutrient uptake problem caused by a too low pH and an accumulation of fertilizer salts in the rhizosphere.

The remedy:

1) Flush the medium.
2) Incorporate Dolomitic Lime.
3) Adjust nutrient solution's pH between 6.5 and 7.0.
4) Incorporate humates (optional, but recommended).
5) Increase nutrient concentration to 3ml/L A + B.
6) Fertilize every seven to ten days (allow for ample run-off)

An alternate remedy: Employ a more suitable fertilizer.

Sincerely,
Charles.
