Fertilizer question

[Snow1576]

Hi all, I bought nutrafin plant gro and I was wondering how often do I put it in the water. Is is everyday? or with every water change?

It depends on the plants really and how much of the nutrients they need are coming from the water and substrate. I like this product and started out with one half dose every water change, but even that turned out to be too much. Now I only dose if I see that plants show signs of deficiency.
