Soil (Canna Terra Plus+) / 10L pot/ Outdor / Big Bull - Kanabia seed 

- watering with pure water only, PH - 6,5

- wastewater PH - 5,8

 

Plant had very good start at begining April but after 3 monts began to change color of leves to yelow and dark braun spots came. I though that happend after stronger winds but it continue till now. And it is critical already. So I stared to search for solution and applied (ones, 5days ago) "Equiprod" as solution agains mold but it doest not help. 

As Im trying to diagnostic and find solution on web..the nearest what I found is that my plant is lack of Mangan. But my PH is looking plusminus Ok. So Im bit lost. Can you help, please.

Those black blotches make me think its a mould spore or fungus issue.... was the grow are clean before planting? 

I think, first off, remove leaves with the black blotches, and wash the plant. Then treat it with some fungicide, google it to find what's best in your area. I'm pretty sure this isn't just a nutrient or bug problem, those blotches are too big, they look infect unfortunately, and need to be treated for fungus

From what I see there mate yes. It could also be a nutrient deficiency, but then you would see smaller patches too, and more orange/ rusty spots.

Give a top dressing of some good compost or something high in nitrogen mate. She looks like she could do with some extra. just add it to the top of the medium and let the microbes do the work

That’s a hungry plant. Be careful with foliar sprays we don’t want to drench plant just mist. Make sure you know those black marks are a fungus or else you might be causing other issues. To me it looks like your plant has been eating itself because of lack of food you know like the meth heads that walk around they have those same black spots.

Like Macky said, do a top dressing, i.e worm castings. Rich soil is good but the nutrients don’t last forever, you need to replenish with organic or fertilizer. 

If you are using a clay pot make sure it’s not overheating in sun, those pots need to be pre soaked in water if you use them too. Plastic blow molds are preferred. 

Remember too that this is science and art. Perfection is seldom achieved the first few times.
