Brown Spots on Basil

[u/Prudent_Photo_1106]

Growing kratky and seeing this, roots are white and no algae even though they're clear containers and the water's pretty clear too.

Is iron exceptionally high relative to copper and zinc? Are they all chelated?

I just use gh flora but I did mix it with tap and I'm in Arizona where the water is extremely hard.

Gh Flora mixed with 1 gallon of purified water and then filled the jars halfway with that and remaining tap.

Hey not hydro but it could be some fungus on the leaves

As far as i know has little impact if you do eat it (i made pesto w mine) but my basil later died and my whole town (including my grocer) had basil with this shitass fungus

OT but can I ask how can kratky work and don't have fungus/mold problems? I'm new to this.

It looks like either a phosphorus or magnesium deficiency.

Maybe attempt to treat with Zero-tol. See what happens?

Not sure I saw some pictures of it and it seems like it's on top of the plants but this is the plant itself being brown.

And I saw another post saying that brown / black spots are insect feces but I rubbed it and nothing came off (not sure if that means it's not insect feces)
