Thought it might have been Phosphorus deficiency but could be wrong, using canna aqua plus Cal mag

Looks like your PH is off. That plant is so jacked up, I don't think it is worth saving.

Are you checking your PH after you add nutes with a good PH pen?

May I suggest you look at my grow, never over 600 ppm, pH around 5.9. You are feeding mutlple times so reduce your rates.
