Looks like a P deficiency..... how often are you checking your ph and how are you testing your ph?
Need more grow information though to be sure.......
For one I would get them out of the cups and into there own pots now.... they gotta be near root bound....... what soil mixture are you using and what nutrients are you using? how often and how much?
What lighting are they under

It's just this one plant,the rest are fine if you wanna check the link in my profile, they have their own cups just transplanted into them, ph is adjusted when nutrients are mixed every 2 days, usually around 5.9-6.0 with a hanna ph/ec/tds meter, they're in coco, using canna coco feeding lightly, watered daily with nutrients, under t5 fluorescents, and the rest of the plant its self looks just fine..
you don't think Ca deficiency?

No, calicum starts on the leaves edges like potassium but the leaves edges have necrotic spots...... P deficiency starts having chlortic spots like that in between the leaf veins.
How much nutrients are you using? what brand?

feeding about 5ml per gallon of Canna Coco A+B and 1.5 Ml Rhizotonic, and like I said it's only 1 plant out of 5 for some reason..

From the pics, I am unable to definitively determine if the issues manifesting on the leaf are starting out as interveinal or marginal. Do you notice if the afflicted one is slightly darker green, overall? I've read elsewhere that excess N can create def of K.
Check out the coco thread originated by this adept person: H3ad goes Coco You may find applicable information there.
Let us now how things go... resolution, etc. That's always fun!

I also wonder if the strain you're growing has any blueberry in its genes.
Only one out of six are showing problems, and I see the familiar looking blueberry twist manifesting in some of the leaves. It's pretty common for strains with anything from the 'blue' lineage to display that kind of goofyness.
Just curious thats all

Are you using r/o water?

Would anyone else reading this thread reconsider feeding at a pH @ nearly 6?herbal essences said:

Isn't that too high for coco?
You grew all these from seed?
H
herbal essences
yup from seed
I've read you can ph coco from 5.5-6.5 so i keep it in the middle of that alittle less usually

Im less than sure thats accurate.....
If you look at cannas pics calcium does not always start from the edges......
Im still keeping an open mind about called calcium defs that start at the edges..... there could be an influence of potassium def....
which most certainly start at the edges........
As far as the ph being too high.....
I dont think that its ever best to let the ph drop into the 5's even with full hydro.....
I think the best range for hydro 6.0 to 6.2
I should answer whats wrong with the plant???
Not a clue......
normally deficient leaves show the same problems on both sides of the leaf.....
this one its only on the right half.....
I wouldnt do anything.... unless it happens with another leaf.......

Well I should of put most of the time, calcium can start on the inner part of the leaves too not just the edges
Reason why I asked if it was from seed is, because may not be as a stable strain and since you are only having a problem with one.... you may have gotten a different pheno.

Do you have any drainage in those cups at all? I see no holes. Holes in the bottoms of party cups are often not enough; go ahead and slice the sides a little too. The medium looks quite wet.
If it were simply Ca deficiency (fairly common in coco), the patches would be longer- like bands usually along the edges- and more yellow to start with rather than that dark spotty necrosis.
When is the last time you calibrated or checked your meter against buffers, a check solution, or another meter or liquid indicator? A friend of mine recently had problems that he ended up tracing back to a Hanna meter that was reading a half pH point low....

If I understand your post, you seem to be saying that calcium deficiency does not always show up on the margins or edges. Could you please cite a reference for this aspect of calcium def? That is, that calcium deficiency manifests itself from the inside of the leaf. I'm not confident this is valid information, hence the reason I ask for a source.MynameStitch said:Well I should of put most of the time, calcium can start on the inner part of the leaves too not just the edges
In general, I believe these issues are more complex than one word answers such as "calcium def". For example, existence of a calcium deficiency does not automatically infer that increasing calcium will be the remedy. Cal may not be the initial cause.

Heres a tip. Plants that small do not need feeding at all and will stay prefectly green.

hey! that's a good tip!
Mine did great in soil before I started nuke-ing it, err, I mean nute-ing it.
It was ONLY THEN, when I had to start learning all this shyte.

Oh... by the way, Happy Birthday, Stitch!
After the celebration, I'd appreciate seeing that source.
Cheers,

This is a link from canna.....
They actually have a lab....I consider the info as good as it gets.....
Click
growinfo
infocourier.....
As far as feeding.....
I feed from the beginning.... how much and what you feed are important....
in spite of the comments plants eat from the beginning..... they should be fed appropriately.......
