Would it be alright to add phostrogen to nettle fertilizer

Question

I have distilled some nettles for fertilizer and was wondering if it would be alright to add phostrogen plant feed to the mix.

Answer 1

The product you're wondering about is made up of nitrogen, potassium and phosphates; you will need to contact the company or your local nursery to learn whether these salts will be good for the plants you wish to feed.
