Urgent:Calcium deficiency or Lockout?

[draxcel]

Canna coco and Coco A+B with hard tap water starting 0.45 EC.
I suspect I have a lockout,or a def.
Would you flush with what?
Lower leaves yellowing and falling off alone.


pH=Always 5.7 to 6.2
Actual EC 1.3
Spots appearing After I tried to correct a low EC runoff of 0.6 in this plant,yellowing at bottom.
So I flushed with Coco A+B at EC 2.0 until runoff=1.7
Spot appeared
Then I changed to 1,4 EC reservoir to not burn the plant.In the meanwhile those appeares.

Hello yes flush with A&B with E.C of 0.5 and how many times a day do you water

 

[draxcel]

4 times every 5 h with dripper.
2 gal pots
Dripper Active for 1 minute and about 250-300 ml of water Is emitted
Temps 24 day /20 lights off 20/4
To flush I have to use 2x amount of water volume than the pot right?
Thank you for answering Coco friend❤

I don't measure It but not too much,like 100ml?
I measure precisely tomorrow.
My last feeding was Just some minutes ago.The runoff was 1.3 EC while going in was1.280 EC.
This Is progressing

Oh,Maybe I have to upp the quantity of runoff too.But Also have to Dial in the flush and restart ti fertigate at 0.5-0,7 EC as you Say.Do you let the starting water into the Total Ec or Just Nutrients EC of 0,5?
