I think it's nitrogen toxicity your plant cannot absorb phosphorus because you have too much nitrogen in soil flush your plant with clean water ph 6.5 to get the nitrogen out.

I guess it is nutrient deficiency. I would add a bit.

You were right. I made flush with Canna Flush and leaves become lightgreen.

Thanks a lot.

After 2 weeks ive got next problem, my plants won't flower! Its about 20 days after changing to 12/12 period but i saw only a few flowers.

Upper leafes are light green/yellow. I changed soil in my pots to BioBizz light-mix after a lot of problems with my soil.

I'm using only pure water without fert. Leafes are damaged by fan.
