alternative nutrients

Hey everyone i was wondering if there was anything i could use around my house to make a home made foliar spray. any luck?

You can use your own urine, yes I am being serious.

really hmm ive heard about watering with it but never spraying it on the leaves. any side effects?

lol just go buy some cheap fertilizers. they really arent that expensive your gonna run into more problems by trying to save $20 with homemade stuff. that shit will fuck your ph levels badly.
