Most nutes that are for blooming are ver inexpensive at the hydro store, I am not home right now but will message you the stuff I use later it was like 19 dollars.
I have heard that urine helps from others but my own exeriance is when a dog pisses on my flowers they die. With that said I am not trying that. lol
Super Bloom I think is used by a lot of folks you can get that at like lowes and home depot if you dont have a hydro store close to you
