Canna Coco Deficiency Help

[draxcel]

Hi Friends.I Ve been feeding and flushing amounts of water to catch my Always lower than inflow runoff EC value.
It Is now 1.6 and inflow 2.0
pH Always on point 5,7-6,1max
Since 10 days I am going Crazy chasing my tail and changing dripper schedule like mad man:The plant Is yellowing from bottom up.I Lost 4 big leaves and Is going up and up.
She showed calcium def (faint def) in veg stage and now It Is stretching(day 40) and showing what seems a Magnesium-P-K deficiency mix symptoms.
Canna Coco and Canna Coco A+B
Hard Tap water(160ppm carbonates) with 25 Mg and 38 Ca ppms
2gal pot.
What Is the problem?A Lockout?

Not an expert here, but have you tried to stay in the higher end of that pH range? It has helped me a lot with Mg def symptoms in coco.

I also find those in my runoff from my fabric pot.A lot of them.Since weeks.
What pest are those?
I have Them in only One plant runoff,the most afflicted by deficiencies.I also have another strain same day but has a less deficiency strenght but the same symptoms except for the Worms in runoff
0 fungus gnats,check Everyday and empty the grow room Everyday.
Got those since weeks

I Always pH down to 5,80.
What pH would you suggest?

While someone more experienced comes by to help you, I think you could try not going below 6.0 for a few days to a week and you should see improvement if pH is actually the cause of the symptom... if it isn't, it shouldn't make it worse either. With my coco which has an unusual low starting pH, I have to stay in the 6.0-6.3 range... I sometimes go down to 5.8 but if I stay there too long I get those Mg def symptoms, but after a few days of going back to 6.0 or bit hgher the leaves usually get back their green and all. Hope it helps.
