I think u have to compost the alf alfa meal first cuz it heats up in soil....I would use high Nitrogen bat guano instead. it has no smell and has a much better N ratio and many benificial soil microbes already inside,,,Does wonders for the soil and ur plant...Fish tank water u can feed to ur plants everyday...I would also not put the epson salt into the mix. I would just folar spray my plants with the epsom salts. Pluss fish emulsion usually has mag inside of it.....but thats a good feeding reg for ur sprouts
