Hello, I have a weird question, we have a 55 gallon fish tank that has hydroponic plants so we put fertilizer in it to help with them I have other plants I use the fish tank water to water them, do I have to fertilize the other plants , if the water I am using already has some in it ?

nope. plants actually love fish tank water in general, so you should be all clear

The plants feed off the fish poop and they actually help keep the water naturally “bio actively” clean😂👍🏼
