r we out doors in the garden soil????????

if so they are planted too close to each other

flush and start folia feeding asap

imho

liquid kelp and worm juice will help

and some activated charcoal to soak up and toxins

 

if your in pots under hydro

flush and start again with a fresh nutrient sollution

flush is crucial

ill add ive used canna coco a and b right through, who else uses it, and ive come to belive its caused be a major nitrogen inbalance and is no good for flowering, canna quotes this

 

CANNA COCO is a complete professional nutrient for plants containing all the essential elements for optimal growing and flowering. CANNA COCO can be used for the growing and blooming phase if it is used in combination with a quality COCO substrate growing medium (like CANNA COCO) due to the fact that it will interact with the growing medium. CANNA COCO is easy to use dissolves directly and is extremely suitable for growing in pots or with ”run to waste” systems

 

i use an ec of 1.3 always and follow feed charts, who else uses it?

thanx for the pix

it looks more and more like salt build up<---leaf curl

please answer my question

r we out doors in the garden soil????????

or what is your potting mix?????????

canna coco a and b right through

if you use hydro nutrients it crucial to use a hydro potting mix too

did you flush again??????????

i can clearly see from the pix

she is suffering shock now

that purple tinge is a sure sign of a K deficiency

 

did she respond to folia K feeding??????????

 

keep searching for insects

look in the root zone too

 

if you are using hydro nutrients then i assume you have a hydro system

do you poor the nutrient solution into the pot and then let it drain to waste???????

or do you have a nutrient solution reservoir and recirculate the nutrient solution thru the pot several times before you let it drain to waste?????????

ive used canna coco a and b right through

if you stick to the plan and follow the directions to the letter

canna coco will deliver

dont try and max her out with supplements

this will lead to problems very fast

if you havent had much experience with hydro systems stick to the recommended plan for your hydro system

till you feel a bit more confident

crucial--->flush regularly

most plans recommend a flush every wk or two

yeah radic i using coco

i run to waste 15%runoff per feeding

yeah im real bad when it comes to flushing, my bad

yeah ive never had a problem with canna coco before

some say its genetics of the plant, or too much nitrogen from the canna coco nutrients

i dont understand why it would be trying to reveg when it never really went into a flowering state.

i havnt tried a folliar feed.

the thing is the sick plant has a sister that is doing really well and right into flowering, all using the same mix of canna nutrients,

the only additive i really use is cannazym or cyco zym, once again ive always used it with no problems before.

ive been advised to buy some different nutrients (dutchmaster) that is specific to flowering, unlike the canna which you use all the way through

 

my ec is always 1.2-1.5 and ph i set at 5.8

 

cheers for your reply i know its sick but would like to try and salvage it so it will flower out over autum

[DurbanDR]

as you can see from the not very good pics, its yellowing and sick from the inside out, the fan leaves are still healthy

i dont know if i could have root disease or something, its just very frustrating!

[Radic]

what is your potting mix???????

i need to know so i can recommend a flushing plan for you

flushing is crucial

i dowit every wk without fail

sometimes more

i have 2/3 coarse sand and 1/3 coco in my pots which drains very quickly so i can feed more often and flush more often

designed especially for the high temps of my hot house and the fast growth rates of indicas

you must flush correctly too

check the link in my signature

give her a good flush

and start again with a fresh solution mixed at 1/2 the recommended strength

folia feed a high K spray asap

go sooooooooooo

[DurbanDR]

cheers for the advice

i use coco

 

am searching for a simple good soil blend at the moment thou

 

cheers
