Where can I find this stuff?

If i needed a fertilizer for a plant, and it need to be an NPK of 20-20-20 where would i find it? And would it be safe with the plant?

your looking for blood, fish and bone. N,P,K all in equal measurements.

u can find it at the fish store

Peters brand fert makes a good 20/20/20,you can get it at growers supply's,ace hardwares,kmart ect.

Ive had nothing but excellent results with all peters ferts.
