Backyard Aquaponics
A place to discuss aquaponics

I added Eco fungicide the other day as a potassium source (although I think I have a phosphorous deficiency, purple tomato plants?), anyhoo I was wondering will it likely knock off any beneficial fungi? I like the idea of my little ecosystem, don't want to muck around with the fungi.

At the rate we use for deficiency I think probably not... it's one level teaspoon per 1000L... it's even less for buffering, I've found about a 1/4 teaspoon in 500L brings it up 0.3, so half a teaspoon in 1000L.

The recommended rate for foliar application as a fungicide is much, much higher than that, I can't remember the exact rate, but it's substantial.

Yes I hoped that was the case but was still curious.

My GB is 2800 and my FT is 7000 so I have erred on the side of caution and added 2 tsp. how often should I do this?
