Fish tank water on the garden

Hi all quick question, when I do a water change I tend to siphon it to a water butt and then use that to water the garden. Thinking the fert (TNC complete) used in the tank would also be good in the garden. But last year I found the plants turned yellow-ey after I had used it on them. it could just be a coincidence but has anyone found the same?
 
I’m currently using it on my potted fruit trees and they seem happy enough, but following closely to see if this might be something I should reconsider!
 
I do too, but I'm also aware my aquarium is very lean - there is probably more nitrate in tap than tank. So don't just assume that aquairum water will have all the nutrients. Water from a fish only tank is probably much better, full of excess nutrients, where are planted tank water may have already had a lot of the good stuff taken up by your aquarium plants.
 
I feel it's something else not the tank water ,possibly plants that shouldn't be in full sun? Lack of fertiliser?l can't recall anything like this and tankwater goes on my potted plants so should show up quickly l would think
 
I have always emptied my waste tank water onto my front lawn. I syphon water from the tank into a yellow 40l bucket, so you can see if you have accidentally sucked something up you shouldn't have (fish, plants, substrate etc), and then pump the water from the bucket, via a length of hose pipe onto front lawn. You can see the semicircular mark of where the hose reaches, the grass is much greener. Also grass is growing right up to the house as this "dry" area is regularly watered.

I use water change water for houseplants but still supplement some extra ferts for the most hungry ones.

Same for me, all <"the rainwater"> that has been through the fish tank goes on the container plants. The exception to this is during the winter, when the volume of "water change water" far exceeds the requirement for watering.

For a fertiliser addition I just use @Happi 's <"Solufeed mix"> (or <"Miracle-Gro"> etc.). I use a <"fairly lean mix">, so I can still <"water the orchids">, Anthuriums etc. with it. <"This orchid has decided to choose life"> and now looks quite healthy (on an occasional slosh of dilute Solufeed).

I still use a <"Duckweed Index"> approach with the house, and container, plants. Any plants that are stronger growers ("have a greater potential growth rate") (Chilli, Tomato etc) just get more frequent fertiliser addition in the summer, when they are in strong growth.
