No ferts used..Babys too lil......

Hey ppl .=)
To get to the point, I have one plant which has reached the flowering stage this week.It has been growing in a seperate pot in my backyard under natural sunlight.I live in Brazil and the season has cut the sunlight to 12/12 now. So i figure the lighting is perfect for flowering.Right?.
Also im wondering if adding ferts now will help/ hurt my plant.?
As I said before Im in Brazil and it is not easy to find commercial ferts here.Whats a good idea insted.Cow crap?They also sell something that I think is worm crap here?<<<dunno Good or No???Also what is a good fert ratio at this stage..?
My plant has only maybe 5 branches that are budding.(my dog did some trimming a month back)It is small (maybe 20 inches) but smells great..Any suggestions on how and if I can make this baby bulk up?Greatly Appreciated Guys=)

There is a user Shakur who grows on a small patio scale in South America and you might get some good ideas on ferts and time of year issues from his grows.
Worm castings are good, and so is cow crap as long as it has been composted. You can make a fertilizer 'tea' of it, or mix it into the soil when you re-pot the plants.
