Yellow fan leaves 3 weeks in to flower

This came on very suddenly in the last couple of days. I'm using coco and the full Canna range. Following the Canna feeding schedule to the letter. They have had quite a long life. Ten week veg, but only 1 of the 4 seems to be affected. This particular plant is also a lot taller. Can anyone diagnose the problem, and maybe prescribe a solution? Thanks in advance

Usually when flowering it puts most of its energy to flowering, its just nitrogen diffency. A common flowering diffency. I would get some guano and add it to the next watering. Should be fine.

Guano? As in bat turd? Is that readily available??

Thanks man, good to know it's nothing too serious.

Yes its readily available. i used Peruvian Seabird Guano from Sunleaves 10-10-2 or some shit liek that. Just dissolve it in water, I mist once a week with it during veg.
