I am thinking nitrogen deficiency?

I am thinking that this is a nitrogen deficiency. It is on a White Widow that I have not fed any nutes due to wanting it organic. I am not sure what to use to rectify this. Ant suggestions are welcome.

Looks it. Use organic nutes. Id give it a side dress of bio live or something like it. Urea is pure N but id feed a complete nute imo

Not sure whats growing around the plant but id yank them out so theyre not stealing food from your widow

If it was my plant, I would get any weeds out of there, sprinkle Espona Garden Tone into the soil. Then a good top dressing of Black Kow and give it a good soaking.

The majority of the nitrogen in finished compost (usually over 90%) has been incorporated into organic compounds that are resistant to decomposition. Rough estimates are that only 10% to 30% of the nitrogen in these organic compounds will become available in one growing season

There are no weeds there. The plant that is growing next to the White Widow is a Columbine. It is finished for the season. I think I am going to try to top dress it with compost and maybe add some high nitrogen fertilizer to the mix. Thank you the replies.
