OK. I understant that it has lots of nitrogen in it, but reasoning behind it when you using fish liquid? Soil what king? Top soil or your own mix. Plants do look healthy though.
Organic soil with miracle grow in a bag. I water once a week with urine diluted with water and fish fert. The rest just water. Fish fertilizer is a liquid it calls for 3teaspoons per gal. I use 4 a gal. Once a week.
I know what fish liquid is, as I have used it before , but only in the beginning. Just till plant were a month old or so. Then I went with fox farms ferts. Very good as I might add. I run with a 12-6-6. Plant will need more ferts as they get bigger. Dose the mg soil have time release nutes. I would Stay away from using urine. I know it might work but not needed with fish liquid. You also might wanna look at getting some cal/mag. I also use more than one ferts at a time. Get some good ferts as soon as you can. Check out my journal if you would like.
