Blue hue on edges and yellowing

Indoor Growing
1

Hi guys,I am using canna Coco A&B+canna pH-(nitric acid) and tap 0,550 EC diluted to 0,4 with distilled water.This autoflower Is giving me Blue hues on edges of new leaves and yellowing from Bottom First leaves.Also It Is same for other 3 girls.I give a Total of 10ml A+10ml B (canna Coco) and 13 ml cannazym for a Total of 1.4 EC that I dilute to 0.9 with distilled.
The runoff Is about 0.840 Ec.I let a lot of runoff water.
Ph 5,8-6-10.
Am I giving too much water or nutrients?

They don’t look that bad from here, maybe a tad too much nitrogen. How much of that pH down, nitric acid, are you using to get the pH in range?

Your input and output pH and EC numbers seem reasonable to me. Perhaps a picture of the whole plant would help us diagnose any possible issues.

Lower leaves are weirdos because It was in Little glassa with soul to germinated and i trasferendo to Coco coir.
I have not checked pH of runoff,only EC.
Yes,I use pH down a lot because my tap water Is hard,also when diluted Is still hard that I have to pH every time I feed
Also purple stems in some leaves

That plant looks great, I wouldn’t worry too much. You may want to get a pH down that uses phosphoric acid instead of the nitric, especially as you move into flower. Otherwise, that new growth can have some off coloring at times.

Canna specifically says to not use their phosphoric acid in their Coco coir because It Will cause troubles,and here I am.They also said No-No to my citric acid…shall I dilute even more the EC?
@ReikoX
Thank you Reiko❤️

You might be able to use less nitric acid if you dilute the tap water 50/50 with distilled before adding the nutrients. Otherwise I would just ride it out.

They look just fine to me. My plants are much uglier than that :+1:

I could do that,I use 30% distilled,gonna head for 40-50%.I doubt about adding calmag if I do dilute more

And the show must go on…a brave soul that can help me?
The Runoff EC Is around 0.9,inflow around 1 EC and 0.9
The leaves became more blueish on top and the lower ones stay green but start to show some blotches (Brownish) like I had in my last grow,those plants ended with CRISPY and fried leaves (only top leaves)
I Ve been giving canna A+B +cannazym at 60% of strenght in a base tap water 0.4
Why so blueish?Need more P?Need to change my nitric acid?Could really be adding a lot of pH down ruining the ratios?
