Stunted Growth & Generally unhealthy

I started 2 planets (clippings) on 11th January.. The roots touched the water/feed on the 17th..

The leaves started to go yellow, I found they had a Nitrogen deficiency so I took a trip to my local grow shop and picked up some Canna Mono. It seemed to do the trick and they started growing nice green leaves again..

But over the last 4-5 weeks the growth has stopped and they generally look unhealthy.
Take a look at the picks below and let me know what you think?
Can they be saved? Any Ideas?

What exactly did you feed them? Looks like hydro, so what PPM and what PH are you at?
Check your air stone, clean/replace/fix if it's not bubbling well.

Looks like you have unbalanced nutrients and the plant isn't happy, or you have root issues from low O2 or PH issues.

Check your airstone.
Empty them and flush with plain water for a few minutes. Make sure to pour some plain water through the salty rocks.
Then fill with balanced veg nutrient water (no extra additives, just basic veg mix) at 5.8-6.2 PH and 800-1000 PPM.

Yeah it's hydro.. the ph is 6.1 in the reservoir.. I check it & make sure it's 6.1 everytime I give them a top up..
I did check the ph of the water inside of the buckets inside of the grow room & it's 4.5? is that ok?
The airstones are working fine too..

I'll try what you said over this weekend. thx

What type of hydro setup are you running? I'm confused how the bucket can be at 4.5 and the rez is at 6.1. The bucket and the res should either be the same thing, or should be connected and circulating, aka the same PH. How is your bucket a different PH?

4.5 is way too low, and if they drifted downward, it's a bad sign. I've never seen PH go down in hydro without root rot.

You probably over corrected for what you saw for a N def, burnt the roots, and npw the decomposing roots are driving the PH lower. If the roots are slimy, make the flush contain a dose of peroxide or bleach and add a good bacteria innoculant (hydrozime) to the fresh nutrient water.

The PH in the bucket is the only PH that matters to the plant.

If it were calcium, wouldn't the water be more basic? Or acidic for uptake?

That buildup isn't calcium, not just calcium at least. It's all the nutrient salts in the hydro. It's a sign that the OP used too much N to supplement the N def he thought he had. Too much nutrients and more salt deposits will form. Also the reason a PPM meter is needed.
 
OP might want to grow organic. Aside from putting a bucket of blood meal on your plant, it's a bit more difficult to burn your plant.

Good call, that adds up. However, if we didn't have the PH info, I could see where Corso's coming from.
 
Looks like nute lockout in the lower leaves and the upper leaves are really dark, so it looks like nitrogen toxicity. The claws are more like spirals, but that just might be that they're that bad.
 
So, Papa Smurf called it, man. You got your answer. It's most likely nitrogen toxicity and salts causing nute lockout from overnuting and the nutes building up. I wonder if cloning a clipping might save something of it? I don't think you can leach out what's already in the plant.

It's not a total goner yet. If he flushes and treats for root rot and corrects the nutrient mix, it will shoot new roots and start growing again after about 2 weeks of recovery. Clones will be a bitch as they aren't healthy to begin with.
