Droopy plant dry leaves in coco. Not looking happy.

3 gallon fabric pot with coco and perlite. I have been feeding canna coco and rhizotonic and giving between 2 and 1 litres.

That doesn't seem substantial enough for the pot size you have. You need a couple litres in waste/runoff in a pot that size, every watering or feeding.

Keep your watering solution the same at 1.2 EC and check the runoff EC next watering, I suspect it'll be high.
In the event it is, you can easily leach the salts out using a mild solution, don't use straight water.

Giving one to two liters is just teasing the plant

Is the pot light when you water ? Have you used a wood skewer to see how close to the top of the medium is wet ?

Without watering to a run off of ~1L it is possible you have a build up issue.

Put the plant/bag on two sticks across a 5 gallon pail and slowly run at least two gallons of just water through.

Let it drain a bit and then "feed" with another gallon.

And start to water to run off in the future

This is not dangerous in any way and you may see an improvement in a few days...
