Brown spots/yellow leaves

I can't get rid of these spots on my mother plant and its turniing a light green/yellow I'm growing with canna nutrients. I have been told it's a cal/mag defiency so I added humiboosta and it hasn't helped...

E.c 1.5
Ph 6.2

Canna a & b
Rhizotonic
Cannyzym

Lol, yeah, that's standard. I've never needed additional cal or mag other than what is already in the nutrient. Anyway, if the whole plant was like that it would be a problem but what you have may or may not require remedial action. Probably more details are required, about the plant. How got to be where it is now.

Canna nutrients suck ass on my opinion. Beyond that, I would suspect that your EC is too high, causing a lockout. A full plant pic would be better though.

Thank you so much for your feedback
I flushed my soil before transplanting and I flushed it repeativly after transplanting and if always maintained a low ec.

I thought maybe it wasnt enough cal/mag If anything. Here's a photo they all have the same problem but the right one in the back row is the worst

So, what's your EC now? What are you putting in?

Beyond that, pick a plant and post any damage you find. I suspect they're all getting the same stuff?

Ec is about 1.3

I'm only useinf Canna a and b Cannyzym and Rhizotonic

I added humiboosta with it and ec went up to 1.6 but that's like once a week house humiboosta. And yes everyplant had it here is another photo

To me, it looks like a Zinc def. if you've been pumping calmag, that could do it. Your nutes Ca/Mg ratio and percentage sucks, but kick it back a bit. Looks like the nutes are there, but most of your metallic elements are being blocked.

I keep my oh at 6.2 during vegetation you think I should drop it to 5.9?

You could try dropping it a bit, see if they pick up. Can't hurt.

Thank you very much brother I'll give it a go and I appreciate the feedback
