Canna fuel CBD (OSS)

Hi all ! after transplantation, the plant began to turn yellow and development stopped, it’s a pity that it was not possible to plant it in a large pot earlier. I replanted them in clean black soil with a small amount of perlite, the pots became very heavy because of this, and in addition, air does not get into such oily soil after watering. I'll try to fix it soon!🤨 I also think this may be due to a lack of nitrogen,
