Is is calcium deficiency?

[JimmyG]

You should have enough calmag. I would leave it out and watch the plants. Mag and cal deficiency are easy to spot most of the time.

No worries - thanks

Hi,
Seems things get worst, I see something similar in other leaf too.
I've changed whole water in reservoir. I've added just a Canna nutrients (Aqua A + B, Cannanzym, Rhiozotonic) - 75% of that what producer said and now there i EC - 1 and PH 5.7.
I didn't add Cal-Mag as it will increase the EC. If calcium deficiency will keep going i will order cal-mag spray and use it.
What should I do if EC go up now in next couple of days? Just add more water or there is something like EC down which I can use (IMHO never seen that before) ?

If you have plant magic cal mag then make that up as a foliar and spray it. Put a drop of dish soap in with it to stick better to 1 litre water and whatever it says for foliar use on the bottle.

You are over feeding, plain & simple.

Ignore charts, they were not written for your plant, more likely a vegetable crop

An easy way to work your ec is start at 0.8 if your water is 0.4 , and keep it at that until the ec in the Rez drops then up it by 0.1 , take no notice of charts and work with what your plant is telling you, multi strains can be a problem as some strains are hungrier than others , your Rez won’t change much with plants that size so keep on low side of ec

The issues with your leaves are caused by fluctuations in your pH. Your pH fluctuates when you have the improper nutrient levels. I agree with those that tell you to lower your EC a bit and see how things go. Don't bother putting extra calmag in at this time. just get your EC squared away so your pH stays more stable and go from there.

Just read this which makes me want to take back my previous advice. My take away from the article that I cannot link is ... filter your water properly and control what you put in it.

"The particular forms of calcium and magnesium that are contained in municipal water are often the large-molecule variety—and large molecules cannot fit into the small pores on plant roots."

Those clay pebbles are bad for ph fluctuations if you don’t clean them properly
