Can you check your links, those aren't working.
Canna coco, flushed 3 times and PH wont drop

Yeah the pics are`nt showing mate.
Yeah Ec14 max Ec incluting the water`s Ec, but max mate. Best to give them a flush until the run off reads the same Ec that you`re putting in, or close (ie fresh water`s EC). Then feed with MAX of Ec14, I`d personally go a litle lower than that. After a couple of days feeding, check the run off Ec against what you`re feeding and if its anything more than .1 or .2 higher, then lower the feed Ec again. The plants should tell you when you have it right this way.

When i switched to coco. i fix a half nute mix of rez formula 6/9 which came out to 3/6 a little calmag...then i flushed my coco to get all the dirty brown/red water out then i squeeze all the water out and dump in my half strength mix..let sit for 30 min to a hour... dump..squeeze all the water out and put in pots...have never had plants as green and healthy ever!!! oh and i learned from a few other especially whodi that the no runoff thing is kinda true... coco in my experience holds lots of water..hope this helps ..peace

OP, I think you are having problems for the same reasons I did when switching to coco. You are setting your pH at the same level as a hydro grow.
For coco, I have found that your nutrient water should be pH'd at about 6.5. I always keep it between 6.3-6.6.
I read a lengthy article recently that showed me the facts. In a coco environment, many of the N-P-K-Mg, can't be absorbed if the pH is any lower than 6.0. Give it a try at 6.5 for a week, and love the results!

got a link or at least a source?
I am not exactly sure where I had read it, but this might help you see the benefits of a bit higher pH range.
Here's a pic of a pH chart that shows the different availabilities:
Notice at 6.5 pH, especially for flower, only Iron isn't 100%.

i am using tap water at 120-140ppm through tall boy. Then i am adding cal mag to get it up to .4ec and am feeding with CANNA A+B now because someone said i should try a coco specific nute to see if i can't get the twisting to go away.

I think that charts like these are substrate-specific. and judging by the line at 6.3, I'm thinking this may be a soil chart.

it also appears that Cal, Mag, and Molyb are also less than 100%, which becomes important due to high number of comments concerning cal and mag.
FWIW, i too have not been very successful with the lower pH values (<5.8) in coco, but i'm still experimenting.
I didnt read this, but I asume your buffering your coco with pH buffer?

can you explain how you water and the frequency? I feel that this is an overall underwatering problem

well at the time those photos were tkaen it was a every two day affair and retardley so. but i wat to take some more pictures tomorrow if i can get the camera. they look lots better but the gdp has some clawing and the sweets are overall great.

here are some pictures, the tacoing in the leaves has gone away, there is still curling on 1 or two leaves, like the wavy curling. then there is also like 2 leaves per plant that are "clawed", the leaves don't look terribly urned except in the tip a little on a few.
at the base of the plant, the new growth is loosing its color a little bit. The thing i am mainly worried about is the purpling in the petioles and the purple lines that are on the stem. Its really buggin me and i can't figure it out.
they are under an 8 bulb T5 plenty of light and are being fed Canna coco A+B at .7 EC. my water EC is .3 so i add botanicare cal-mag plus until it goes up to .4 EC as per the instruction canna gave some guy in another thread.

can anyone shed some light on if this purpling is normal for sweet tooth
