Adding pee water to a container...

Just planted out some pepper starts, and they are already showing signs of  nitrogen deficiency.
The leaves are all turning light green.
These are in large 25 gallon sub irrigated planters, a long with  some tomatoes,so the perfect setup for nutritional deficiency.

I have plenty of rabbit dung to top dress, or dig in, but will that be available fast enough to save these peppers?

I'm considering  watering with pee water, or moving the peppers, or both.

Any idea if pee water would make more nitrogen available more quickly ,than the rabbit poop?

Hi William- I asked about this topic recently and got very helpful replies (as is usually the case on this awesome forum!). Here is a link to the thread:

The diluted urine worked very well. The plants really took off.

Thank you so much!
I forgot/missed that thread, its just what I needed.

Well yes, but I have also burned seedlings with diluted pee-water, and burned seedlings don't recover. Maybe it wasn't diluted enough: a few days later I could see that overfertilised salty look (slightly discolored soil with a tiny bit of white crust around the edges of the container) . I think one issue might be that since I plant seeds in pure sand, there's no organic matter to handle the input. Established plants in soil with organic matter seem to always welcome diluted pee-water.
