Fish Poop Qs

ok i have this soil mix that i mixed about a month ago, becaue i wa plannin on uin it then. but its still ittin around and i want to use it pretty soon, my questions are this. firt of all i mixed a good bit of 5-1-1 fish fert. in to the mix. i might alo mix some 2-4-1 in. im plannin on diggin out a hole and fillin it with this stuff, and then puttin my big ol girl in the ground finally.. im jut wondering if the fish shit is still legit. and im also wondering if havin it in the soil could cause too much nitrogen later on. also if anyone has any good suggestions for a potassium source.

emusion is good, and fairly mild, so you probably wont have to much problems with having too much nitrogen, even when flowering plants need some nirtogen...

right, thats what i figured. thanks beanman
