I used to only use a tiny bit of fish at a time, but my plants were really yellowing earlier this season so I went ahead and just put a shit-ton on them the last month, like half the bottle. it says right on it, it wont burn them. I dunno if I would trust it real strong in pots tho, I know in the ground it all gets diluted. I also watered like 20 plants with it so I dunno how much you should use but 3 tblspns a gallon should be the max I'd imagine. but anyways I would recommend age old grow and age old kelp to add with it. I've been using the kelp the whole time but couldnt afford any grow. luckily tonight one of my old hydro shop friends hooked me up with a couple gallons of tea he made which is a mixture of age old grow, fish, kelp, aurora amino acid blend, vermicrop, and a couple other organic nutes mixed in. and a whole sammich baggy of myco. also he gave me a 5 gallon buck of heavy harvest but I dont use chemies so I will probably save that for a friend or a guerilla grow since it doesnt attract animals like organics. either way I came up on a good $400 worth of nutes. It never hurts to ask a home-boy for help. " the squeaky wheel gets greased".
