as for the fish stuff that is more then enough to keep the soil micros happy
as for what the nanners add to the soil i did not know ........there is one thing u should be warned about ......with autos if u add the right things the plant's maturing rate slows prolonging the life of the plant (u get denser sticker buds but time tables are off.....make sure u scope the plant and do not premature cut it down .....ideally the plant will tell u when done yellowing of the fan leaves reach middle of the branches )
